Who do I contact about getting the right extension bar? The one I ordered Is a 2 1/2 inch which I need a 2 inch to slide into my receiver or if you guys have a 10 to 12 inch, 2 inch extension so I can connect it I sent a photo of the end that is 2 1/2 which I need it to be 2 inches to slide into my receiver

I do have an extender that will work for you. It is part # C45796, however is 18 inches long. I will have our Customer Service team reach out to you to send over return instructions.



by:

Received the product on time and as described however two days later I found it on Amazon for $167 vs the $XXX I paid from
etrailer. When I called to see about a price adjustment - they couldn’t assist and offered return and re-purchase from Amazon - minus a $XX return shipping. Lesson learned.



by:

I recently swapped out the stock 2" receiver for a 2-1/2" to allow me to purchase and use this extension to get past the end of my Lance 1010 Camper. I believe I will have no issues now towing any trailer (within allowable spec's) or carrying my motorcycle carrier. Great quality piece. can't wait to try it out...

Excellent! After a year of use still happy I purchased this product...Had to cut it to match the length of my campers overhang but it is perfect now....



by:

Love it! I don't have a slide in camper or truck attachments. I simply purchased to increase turn radius and how much I can cut the trailer before jack knifing, works great for tight spots.



by:

only using for bike rack with my Truck Camper. Great fit and exactly what we needed.



by:

This worked out great for my trip from Minnesota to Montana and back, wouldn’t have been able to do it without it



by:

works as expected, i was worried about trailer sway with the hitch having some wobble, but pulled up to 70 just fine. I like the fact that i dont have to use the factory adaptor on the receiver.



by:

Great service, price and prompt delivery. Hopefully will help immensely with getting my boat off of the trailer during winter drawdowns like the picture.



by:

Great extension just had to cut off about an inch to fit it on my truck. I did not receive the pin for it.



by:

Works nicely with my 19ft lund boat and a 10.5 ft camper on the truck. More solid than I thought it would be. I use it full length. Works great.



by:

Exactly as described and I custom tethered it to the camper bumper for more stability. I did have to drill out the pin hole a little as it did not line up 100% to get the pin inserted, but it is going to work very well.



by:

Excellent product. Easy to use. I recommend finding someone with a metal band saw to cut to length. I cut mine with a sawzaw metal blade and finished it with a high grit sanding disc and it turned out ok- not perfect. I towed my boat behind my truck with the camper on it and it worked good. I’ve also attached my motorcycle rack with my 2013 ktm 450. To be on the safe side calculate your tounge weight before towing.



by:

Great product, worked out perfect for extending passed the cab over camper.



by:

Product is heavy duty, and, tho I haven't used it yet, I expect great results like previous reviewers. Price was good and customer service dealt quickly and favorably on a small issue I had.
I did have to cut 1 1:2 inches off to make it fit in front of my spare, but that was no surprise because I read that other buyers had dealt with the same issue. Chevy/GMC trucks spare tires get in the way a bit. Very satisfied. Have bought from etrailer in the past and don't think they can be beat. Thanks to Caleb for his help.

Really well. I just used it to tow my boat halfway across Washington behind my pickup camper and it worked great. I’ve used it several times now and am very happy with what it allows me to do.



by:

Super happy with etrailer who helped me select this hitch based on my needs. It’s perfect for me. Very solid, well made hitch extension. Packaged appropriately and protected. The paint on this hitch is awesome. Only flub is the end of the hitch needed to be trimmed. My F250 spare tire got in the way of the back length of the tubing, so I had to cut off about 1/2”to clear the tire. Otherwise it looks great and operates as expected. Good price point too. Thank you for all your help etrailer !



by:

Gave it 4 stars because I have never owned one before so I have nothing to compare it to. It works good, really seems to ground the truck. I have a Ford F250 superduty crew cab with a 8 1/2 ft Lance light camper that sticks almost 2' past the bumper and I pull a 18' open trailer with a race car on it.

CURT C45048 HITCH EXTENSION I drive a 2011 GMC 3500HD with an S&S 9.5 slide in camper. I needed an extension to be able to tow my boat behind the truck/camper. I saw this extension was on sale w/free shipping. I ordered on Sunday 9/10 and received it on Wednesday 9/13. The extension looks very heavy duty and it slipped right inside my vehicle receiver. The extension protrudes about 4" past the camper bumper. PERFECT!
All of the welds look like quality welds. I just need to mount my trailer harness and I will be ready to go! Great service, great prices & delivery!

The hitch extender is still doing a fantastic job! Very happy I purchased this product.



by:

This product works great however I would not go over the weight limit. I try to stay well below it remember it's not a super truss.



by:

Packaging was very poor, 32" extension hitch just thrown in a box. No projective packaging around it. Paint chipped off reciver end. Box taped up in areas that were damaged. Extension plug completely out of clam shell packaging, not damaged luckily. Seriously, you need to do a much better job of wrapping and protecting parts.
Very disappointed.

I am very sorry that the hitch extender arrived with paint damage. I will have our customer service team reach out to you. I recommend using a rust resistant paint like Rustoleum to touch up the affected areas to help protect against corrosion.



by:

mostly impressed with short shipping time and the sturdy box it came in



by:

Great fit no alterations necessary to fit my HD 3500 standard bed.



by:

Absolutely the correct product for my needs. This fit perfectly beneath my Lance truck camper enabling me to haul a 16 foot trailer behind. All the holes matched up to my Dodge RAM 3500 receiver, and because the full length was necessary, no cutting was required. This was, by far, the least expensive bar at this length. Delivery was fast. I have no complaints--only good things to say. Thanks.

Sandee

This product continues to be a valuable item. It is very durable.



by:

This extender works great with our 2019 Ford F350 when using our 9'6" truck camper so we can use our bike rack or tow a trailer. Nice product, great etrailer selection and info once again!

Used with my new slide-in truck camper while pulling a cargo trailer. Worked well no problems with the product.

Works great, just as expected.



by:

Does what it's supposed to. I got it to tow my 3000lb boat when I have my pickup camper on. With this I don't have to crawl under the camper to hook up the boat. I did a 1600 mile round trip a few weeks ago with no problems.

  • Hitch Extender for a 2015 Ford F-350 Towing with In-Bed Camper
    For starters, the TorkLift Cannon Hitch Extension part # TLE1636 that you referenced is only designed for a 2016+ Ford Super Duty with the 3" receiver tube. According to my research, the 2015 Ford Super Duty only comes with a 2-1/2" receiver tube so it does not appear that the TorkLift Cannon Hitch Extension will work for you. Instead, you would want to consider the Curt Hitch Extension and Reducer part # C45048 which measures 34" from hitch pin to hitch pin and has a 6,000 lb weight capacity...

  • Recommended Hitch Extender for Towing/Hitch Accessories With Truck Bed Camper
    Both the Curt # C45048 and the Reese # RP45292 hitch extensions would require using a 3 inch to 2-1/2 inch reducer sleeve # BWRHXA2183. This would work pretty well for towing but it would allow a hitch mounted accessory like a bike rack to bounce about quite a bit which would concern me. The bouncing force would increase the leverage applied to the extender and the hitch installed on the truck, so I'm not thrilled with either of those two solutions. I'd prefer to see you use an extender...

  • Recommended Hitch Extender For 2018 Ram 3500 DRW With Max Tow Package
    Based on all of the information I was able to find on your 2018 Ram 3500 DRW with the max tow package your truck should have a 2-1/2" trailer hitch receiver. For a 2-1/2" receiver you will need the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048 which can be used as a 34" extension of cut down to a 24" extension. This extender has a 450lb tongue weight and 4500lb trailer weight rating or 600lb tongue weight and 6000 trailer weight rating when using...

  • Can Curt Hitch Extender part # C45048 Fit Into Factory Hitch of 2003 Dodge Ram 2500
    If your 2003 Dodge Ram 2500 has a factory hitch that has an opening that measures 2-1/2 inch by 2-1/2 inches the Curt hitch extender part # C45048 will simply just slide into it. The 2-1/2 inch hitch size is pretty common on newer heavy duty trucks like yours but due to age of your truck it's probably a good idea to measure yours first to be certain. This is designed so that it can be used as a 34 inch long extension or cut down to a 24 inch extension and provides a 2 inch hitch opening.

  • Using an In-Bed Camper while Towing an Enclosed Trailer with a Chevy Silverado 3500
    For your 2001 Chevy Silverado 3500, I highly recommend Torklift # TLC1205-30. The SuperHitch Magnum has more than enough weight capacity to tow your trailer with a hitch extension. For your hitch extension TorkLift # TLE1524 is the most solid option to carry your enclosed trailer. The SuperTruss needs to be used with # TLWD1000, which is a weight distribution system. Your trailer is too heavy for the the Curt hitch # C15703 paired with a normal hitch extension like # C45048 because you...

    The Hitch Box Extension and Reducer for Titan 2-1/2" Trailer Hitches, 24" - 34" Long # RP45292 or the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048 will work for your truck and trailer as you described it, but I recommend the Reese because of its higher rating. The measurements are from hitch pin hole center to hitch pin hole center. We measure this way because the hitch receiver can have different dimensions from the hitch pin hole to the end...

  • Recommended 18" Hitch Extension for 2018 Toyota Tundra and 530 Pound Tongue Weight Travel Trailer
    For your 2018 Toyota Tundra this is safe as long as you are not exceeding the maximum tongue weight on your hitch or the extender. There are several available 18" extenders. Only two of these will meet your required 530 lbs tongue weight, and that is only with the addition of weight distribution. I recommend the # ST18 Brophy Hitch Extender with Step. This has a maximum tongue weight of 350 lbs but you can increase this to 700 lbs with weight distribution. This meets your 530 lbs tongue...

  • What Wiring Harness for Curt C45048 36 Inch Hitch Extender
    I'd use a 7-way connector loop like # 20027 as the easiest option that wouldn't require cutting and splicing. At 7 feet, it's longer than you'd need but you can wrap the excess around the extender which will help keep everything secure. One end of the loop would connect to the 7-way in the vehicle, and the other end will attach to the bracket affixed to the # C45048 extender.

    If you could get by with just a 34 inch extension we have the Curt part # C45048 which would fit your hitch and has the weight capacity you'd need and would be a really simple solution. If you do need a longer extension you'd have to go to a Torklift trailer hitch like the # TLF1008-30 so that you could use one of their extensions like # TLE1536 which is 36 inches long. If you absolutely have to have 36 inches of extension this is the best way, but if you could get by with 34 inches the...

    We do offer hitch extensions for the factory 3" trailer hitch receiver on your 2017 Ford F-350 Super Duty, but there is not one that is 24" long. The shortest extension available is the TorkLift Cannon Hitch Extension - 3" Ford Super Duty Factory Hitch # TLE1636 which is 36" long. This hitch was designed specifically for your 3" receiver and has a tongue weight rating of 360lbs and a trailer weight rating of 3600lbs.

    For your Ford F-250 with truck bed camper, the Brophy Hitch Extender with Step - 2" Hitches - 18" Long - 6-1/2" x 17" Platform # ST18 will get you out from your camper with a towing rating of 3,500 lbs which will not be enough for your Jeep. If you happen to have a 2-1/2 inch hitch, then you can use the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048 which will give you a 6,000 lb towing capacity at 24 inches which may be enough depending on your...

    The Curt Combo Bar # C49360 is generally used as a weld on receiver for custom applications on trailers, RVs, or service vehicles. I spoke with Curt and they have not tested the # C49360 as an extender, so they couldn't give me any specifications as to capacity as an extender. With that being said, I cannot recommend using it as an extender. The Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches # C45048 may be a better option. This arrives at 34 inches long, but can also be trimmed...

The Brophy Hitch Extender # RHE12 (14") will reduce it by 33-1/3% while most others will reduce it by 50%.

If your hitch on your popup camper is 2", then this extender will not fit on it. We have other 32" long extenders that fit into 2" hitches, but they do tend to be pricey like the TorkLift SuperTruss Hitch Extension- 36" Long # TLE1536.

    I have a solution for you, but the TorkLift # TLE1642 is designed to fit in a 3" hitch receiver and reduces your hitch down to a 2-1/2" receiver. If you're looking for an extender that fits in a 2-1/2" receiver and will reduce it to a 2" receiver, the Curt # C45048 would be what you're looking for. It does not appear that we have anything available that will extend a 2-1/2" hitch and not reduce it, nor is there an extension that would make the receiver larger.

    We have a Curt hitch extension part # C45048 which can be cut down to 24 inches like you'd need. But you'd need to have a 2-1/2 inch hitch installed on your vehicle. It looks like you have a 2008 Ford F-250 or 350 so if that were the case you'd need the part # C15810 for a hitch that's a fit for the vehicle and compatible with the extension.

Ball mount # BM20 measures 13-1/4' inches from the center of the pin hole to the center of the ball hole. It is rated for 10,000 pounds gross trailer weight and it has a 3/4 inch rise or 2 inch drop.
