We're fulltiming in a 2006 Heartland Bighorn 3600RL fifth wheel, being towed by a 2006 Dodge 3500 CTD. The Bighorn was delivered in April 2006. It's 38 ft long, has 4 slides and weighs approx 14500 lbs when fully loaded for travel. It also has a TrailAir pin box and Mor-Ryde suspension to smooth out the ride. The truck has a 6 spd manual transmission, single rear wheels and a Husky 16k pivoting fifth wheel hitch. We also had to install a 2" receiver hitch on the front of the truck to accommodate a Yakima dry dock for the kayaks.  Our kayaks are carried over the cab and hood of the truck and bicycles are attached to the ladder on the rear of the RV.
