Today we're going to take a look at the replacement side plates for the Demco Hijacker Autoslide fifth wheel trailer hitches, and this is for the underbed mount. Now this will replace the side plates that came standard with your Demco Hijacker Autoslide underbed fifth wheel trailer hitch. They are designed to bolt onto your hitch base so that you can attach your hitch to the custom underbed rails. This is designed to fit the 13,000 pound Hijacker, Part Number DM8550041. It also fits the 18,000 pound Hijacker, DM8550022, and the 21,000 pound Hijacker, DM8550037 models. This is a simple bolt-on installation to your hitch base. There are multiple rows of bolt holes on these side plates and on your hitch base, so depending how you line them out, it will let you adjust the hitch height.
The hitch height settings will go from either 15-1/2 inches to 16-3/4 and 18-1/4, so you have your choice of those three settings to get your trailer and tow vehicle as level as possible. These do have a rust-resistant black powder coat finish. They are an all-steel construction. It does include the instructions. It will include the mounting hardware, and it also includes two 1/4-inch spacers and two 3/8-inch spacers, and the spacers are used for adjusting your hitch mount with the bed pockets of your truck, and this part is made in the U.S.A. The way that these would open up is you just pull the clip, pull the pin out, and you can see each one of these will rotate out, and when you rotate those out, it will let you drop it into your underbed mount, and then once there, you just turn this back in to lock it, and then put your clip right through there just like that. This part is made in the U.S.A. That should do it for the review of the replacement side plates for Demco Hijacker Autoslide fifth wheel trailer hitches with the underbed mount..
After a year, I still like my Demco autoslide. It works great. I have pulled my trailer quite a few times and have had no issues at all. I know quite a few people that pull 5th wheels and one actually went out and purchased a autoslide after watching mine work.
This hitch has been used daily since i purchased it. I deliver fifth wheel travel trailers all over the country. This hitch has worked flawlessly from day one. This hitch is one of the only products that I've ever bought that is exactly what it was described to be. Im not one to do reviews, so the fact that im doing this one , in itself, says a lot about the quality of your product. The design and looks are much better than any other hitch ive seen. It just looks better in the truck bed than others do.
Instructions left alittle to interpretation when it came to hitch height in the bed of the truck. For a f350 super duty it is the medium set up. Save you some time and effort. Other then that it looks great and will be testing it out this weekend.
Hitch works great. Had some issues using it when I first got it with putting the pin to lock down the handle but its worked much better lately. The hitch is heavy so I leave it in the back of the truck. Wish I could remove it so it doesn't get weathered.
Hitch looks great and functions great as well. Installation could’ve been smoother due to the installation instruction measurements being slightly off. Look at finding hole caps that are 3” instead of two and drilling the larger hole.
great hitch for my customers new truck to pull his new Durango 5th wheel!
Fast Delivery as well
Always RV

Hitch sucks pain in the assembly to connect and disconnect.
Great functional hitch. Poor powdercoating though (mostly flaking off) with quite a bit of rust after only a year.
Well built fifth wheel hitch. Haven't got a chance to tow our new Montana High Country 295RL. But I know a guy that has towed his fifth wheel with this same hitch. I'm sure this 18K hitch will be excellent! Or I wouldn't have bought it. I recommend e trailer for everything.
Demco auto slide hitch works very well with my crew cab short bed Ram. Fits under my tonneau cover nicely. Trouble free thus far. Had to purchase a Demco plate for the camper to make the Rhino box hitch work. etrailer personnel were great in helping ensure I had the right products and kept me well informed of shipping dates.
A very nice hitch. If you have a bed carpet or a bed liner it may require Un shimming the locking pins. I have a bed carpet and I had to stand on the back corners to get the pins to engage the bed pucks. Not really a big deal. It is very heavy so I assembled it in the bed of the truck. I would highly NOT recommend doing it this way except if you are by yourself. Get a chain hoist or maybe an engine hoist because it is very heavy as an assembled unit. It is flawless in its operation. Very well made. I am very happy with it.
LOVE, LOVE, LOVE IT. I purchased 2 different 5th Wheel Hitches before I purchased this one. After hitting the cab of the truck, I wanted to get a slider. I did my research for several months and just kept coming back to the Demco. This hitch automatically makes the adjustment when I need it, even when I don't realize I need the extra room. I never have to get out of the truck to release the hitch to slide back. I put the hitch together with no problems, of course it came about put together anyway, and the Instructions were good. the locking down ont he truck seems to be easier than other I had. The only regret I have is that I didn't buy this one sooner.
Item works exactly as described. I have a shortbed (6.5') Ford F350. Probably towed our 5th wheeler 5000+ miles with no problem. Then last year it happened! We were making a sharp turn in an uneven lot and POW, the 5vr hit the rear window and it exploded. After that I became gun shy about turning with the 5vr attached so I started looking at sliding hitches. A slider that you had to get out and unlatch to make work, didn't make sense to me. At what point do you get out? So, an auto slider hitch was purchased. Now when I get to a certain degree turn the auto-slide hitch moves back in its carriage and then auto-slides to the normal location once straightened out. Not gun shy anymore.
Pro:
Well packaged
Well made
Easy install
It WORKS.
Cons:
Price
Very heavy
Some clunking after it straightens out from a turn
Very happy with my Demco Autoslide hitch after one year. We pull a Montana 3120 35 ft 5th wheel with a 2019 Ford F-350 short bed. Took a month long 6,000 mile trip from Colorado to New England/Canada this Summer. Lots of hilly/curvy roads and some remote campgrounds with tight corners and some near 80 degree back ins. Never came close to trailer contacting the truck. I’ve had no jerking or other issues when turning or stoping/starting. Works great. The only drawback is there isn’t much room for error when you back up to hook up the trailer, so it takes a little practice to get used to correctly lining up your Demco Hitch to the trailer. The first couple of trips, it took me 3 or 4 attempts to properly line it up. No longer an issue for me after a few trips and you get used to the angles. It weighs about 300 pounds. I got a small chain hoist which I installed in my garage rafters and easily lift the hitch in and out of my truck and just let it hang front he rafters until I need to use it.
This 21K unit is very well built. It does have some weight to it so some help installing would be much easier.my installation was completed solo and took approx 1 hour in a GMC 3500 Denali.
The Demco Auto slide takes the worry out of towing my fifth wheel trailer with a short bed F-350. I have had no problems with backing into tight camping spots. And since everything is automatic I have one less thing to worry about while traveling with a fifth wheel.
The only problem is that it is a little on the heavy side, so I just leave it in the truck when not towing. Problem solved.
I am extremely happy with the product.
Solid hitch and fits as expected. Only 4 stars due to the limited hitch up angles. You really have to be within about 5 degrees of straight with the hitch in order for the system to function. Did not have this much of a problem with my other auto slide hitches, but this is the only one I could find with the weight rating I needed for my combo.
This review is for the Demco Autoslide 21k and accompanying OEM rail adaptor I purchased for a 2020 Ram 3500 Megacab DRW. I've owned it one year. Overall, the hitch performs as I expected. It is high quality, very sturdy and seems like it will last for a long time. I had it installed at the dealer when I purchased the truck. It automatically slides to protect the cab in my 6'4" bed without any incidents. I tow a standard fifth wheel RV. There are a few negatives, which are not necessarily shortcoming of the product but, instead, necessary evils to allow me to have a short bed. First, it is BIG and BULKY. I believe this is just a function of the mechanism required to allow the autosliding feature and I am not really sure there are any other lighter alternatives with this feature. The fact it requires two parts (OEM Puck Rail and hitch), make it even more bulky. It takes up almost the entire bed and prevents most auxillary tank / tool box combos from fitting. Even standard size storage bins will not fit in my bed. I would prefer if they had a custom OEM all-in-one hitch for my truck like they do for the Ford. It adds significant weight, which decreases carrying capacity, which can be at a premium in hauling a heavy fifth wheel. I've never even tried to take it out of the bed due to the weight and difficulty. I also am not very happy with the adjustable catch plate design. It requires significant manipulation loosening and tightening 8 nuts when hitching and unhitching. This requires a step ladder to reach the nuts. I also found out after the fact that it does not come with the right size catch plate attachments for my hitch and I had to purchase a separate part, which added unexpected expense and delayed my taking the RV on its first trip. Overall, I am satisfied with the hitch.
