Remarks about the 3055rl model. We have 2008 3055rl, and use a F-350 Diesel SRW with the increased 11,400 GVW, 16,000 lb Reese hitch and the unit sits very level when hooked up to the truck - which keeps the weight pretty even on both 5th wheel axels. It looks like the pin box on the 5th wheel has some adjustment capability so your dealer should be able to deal with any height issue you are concerned about. As for the 3055RL, we have been VERY satisfied with the unit, and it has served us well without any major problems. One consideration on the floor plan - we like the fact that you can make a short stop while traveling, use the entire kitchen, dining table, fridge, microwave, bathroom, bed, without bumping any slides out. After over 25,000 miles of traveling, that is a nice feature. Recommendation: once you get your unit, loaded and ready for travel, fill your fresh water tank, propane, and your truck fuel tank, then run it across some scales - most truck stops (Loves, Pilot, etc. have scales and get 2 weights - the total of everything together, and the weights of each axel. Unhook the 5th wheel, then weigh the truck by itself, then check the weights against your truck and 5th wheel limits.
Modifications that we made: 1. Removed the closet shelf, and installed a very heavy duty (1/2 oak plywood) closet "organizer" that gave us more hanging rail space, drawers, etc. The shelf brackets/hanging rod that came with the unit just wasn't strong enough to support our clothes weight while traveling. 2. REPLACED the "china bomb" load range e tires with some heavy duty load range g 14 ply tires. 3. Added the Rieco Titan heavy duty electric jacks. 4. Installed a Honda 3000 generator in the bed of the pickup. Other than that, the unit has been perfect for the 2 of us (we are not full timers). Good luck with your new unit, and this forum is a great place for more info.
