Recommended Weight Distribution System for 28 Foot Travel Trailer Towed By 2007 GMC Sierra

Question:

I just bought the EVO use and pick it up in two weeks. I m prepping the GMC now... got a Tekonsha Prodigy P2 and wiring it up! Im looking at getting the Pro Series PS49582 because I think the specs are OK? The TW on the T2360 is advertised at 548lbs... but I m not sure what it will be when I load the trailer, so not sure what to use as a reference when getting the distribution system? Also, I noticed a comment in one of the answers about the need for two friction devices for longer trailers... the EVO comes in at 28ft - need the extra? Thanx ahead of time!!

To choose a weight distribution system, you'll need to first determine the fully loaded and ready to tow tongue weight of your trailer. To that figure, add the weight of any gear stowed in the truck bed behind the rear axle. I've linked to an FAQ article that explains how to do this. These combined figures make up the Total Tongue Weight (TTW) of your set-up. The TTW of your trailer should fall as close as possible to the middle of the effective range of the weight distribution system you choose.

I'm assuming that the 548 lb TW you mentioned represents the TW of the trailer without any gear, with empty water and propane tanks. The fully loaded TW could likely be quite a bit heavier.

If the TW is 750 lbs or less, the # PS49582 you mentioned would be a good choice, it's what I'd consider an entry-level system.

A Reese Steadi-Flex system, part # RP66558 for TW under 600 or # RP66559 for TW ranging from 500-1000 lbs uses an integrated sway control system that would do a better job of controlling trailer sway that the friction units used on the PS40092. Longer trailers with tall sides like your camper are especially susceptible to crosswinds and turbulence caused by passing traffic. Both systems include the weight distributing shank, but the trailer ball is sold separately. For a 2 inch ball, use part # A-90 or # 19286 for a 2-5/16 inch ball.

If you decided to go with the PS49582, I would recommend a second friction sway unit, like # 83660.
