• Does the K-Source Custom Extendable Towing Mirror Sit Level on a 2006 Cab and Chassis Sierra 3500?
• No, it does not. The Passenger Side K-Source Custom Extendable Towing Mirror item # KS62073G tilts in slightly to follow the contour of your Sierra 3500's A pillar. I attached a picture below so you can see it installed. It's slight but definitely won't be level. This is just for the passenger side. If you need the complete set you will want item # KS62073-74G.

• Recommended Aries Nerf Bars for a 2005 GMC Sierra
• It won't fit because the brackets are completely different. The 2008 GMC Sierra's are a different generation than a 2005. GM made some significant changes to their trucks for the 2008-2013 generation. These are designed to be bolted on only, no drilling, to supports and mounting points underneath your truck. They'll be in different locations and most likely a different size on the older trucks. The bars themselves also follow the contour of the trucks body which changed with the new generation. We...

• What is Weight Capacity of Tow Ready Safety Chain Kit # 49150
• We don't rate the Fulton chains we offer like the part # FCHA0050324 that you mentioned. Fulton is who tested and rated the chains for 18,800 lbs. They are normally very conservative with how they rate their chains and towing products and we've yet to have any issues with that so I'd feel very confident in the 18.8k capacity.

• Can You Determine Tongue Weight of a Trailer if the Trailer is on an Incline
• Since your trailer is sitting perfectly level, even though it is on an incline, the tongue weight of the setup will be accurate if you were to weight it as-is. If the nose of the trailer was high or low the figures would get skewed. You will need to somehow get the scale to sit perfectly level as well for an accurate reading which could prove challenging. You should note that any weight from cargo behind the rear axle of your tow vehicle will need to be considered as tongue weight. Since...

• What Trailer Weight Requires Brakes
• In the USA a tandem axle utility trailer with a gross vehicle weight rating (GVWR) of 7500-lbs should have brakes installed. Any trailer over 3000-lbs must have brakes on all wheels in most states, but laws do vary. Some states require braked axles on trailers with a GVW as low as 2000-lbs; other states have a higher limit. It is best to check with authorities in your local area. The weight of the tow vehicle can come into play here too. Often the gross weight of any such trailer without...

• Pickup Truck for Towing Grand Design 5th Wheel with 8500-lb Dry Weight
• Generally we recommend 3/4-ton long bed trucks for 5th wheel towing. Although the 2007 - 2013 Sierras with 6.2L V8 have 400+ horsepower (enough power for your trailer's weight) the short bed makes maneuvering the 5th wheel a challenge since you have reduced turning clearance. Short bed trucks CAN be used for 5th wheels by using a slider hitch or better still a Sidewinder. A Sidewinder replacement pin box extends the pivot point rearward from the hitch by 22-inches, almost double the additional...

• Can Demco Recon 5th Wheel Hitch Safely Tow 20K GVWR Toy Hauler
• You are correct that the Ranch Hitch # AM3100 adapter is not compatible with the Tri-Glide pin box as it was designed to be used with standard pin boxes only (nothing cushioned or with an air bag). It is important to have some cushion in weight capacities when it comes to any kind of towing and the 21K Demco Recon # DM8550045 will have 1,000 lbs of extra capacity if you were to load your 2014 Dutchman Voltage V3990 all the way to the 20K capacity. With all of that being said, it would...

• How Much Weight Can You Put On Top of the TuXport Soft Tonneau Cover # TX281601?
• I have a solution for you. Technically, the TuXport Soft Tonneau Cover # TX281601 can hold up to 200 pounds of evenly distributed weight on the cover and will fit your 1999 GMC Sierra (8-ft. bed). However, there would be difficulty with securing the kayaks to your truck without a crossbar system. With that being said, the safest way to transport your 2 kayaks would be a ladder rack system like the Adarac Custom Truck Bed Ladder Rack - Steel with Aluminum Crossbars # A70570. The Adarac...

• How Far Down Does Curt Trailer Hitch C15323 Hang from Frame on a 2002 GMC Sierra 2500
• First I should mention that Curt trailer hitch # C15323 will only fit your 2002 GMC Sierra 2500 if it is an LD (light duty) model. It will not fit a 2500HD (heavy duty) model. But on the hitch it measures approximately 6-1/2 inches from the rear most attachment point (on the vehicle) to the top of the cross tube and 9 inches to the bottom (the cross tube is approximately 2-1/2 inches square). Take a look at the picture I added with these measurements.

• Tongue Weight Capacity when Using Titan Trailer Hitch Extension RP45292 with Weight Distribution
• A weight distribution system is used to more evenly distribute the weight of the trailer to all axles of the trailer and tow vehicle. When using the extension, # RP45292, the tongue weight capacity is going to depend on the length the extension is cut to. If it is cut down to 24 inches, the tongue weight capacity 600 pounds. At the 34 inch length the capacity is 450 pounds. It does not sound like you have a weight distribution if you are using the extension and a ball mount and are connected...

• Recommended Air Bags for Cold Weather on a 2012 GMC Sierra 2500

Like tires you may see a decrease in pressure do to extreme cold temperatures. As far as road salt goes Air Lift makes special kits with stainless steel mounting brackets and lines.
