Deb, We have a 2005 Ford 2500 Lariat, 6.0 Turbo Diesel, 4X4 SWR. According to the charts we are rated anywhere between 14,200 and 15,600. The max weight on the BH is 14,000 wet and 10,500 dry. Should be alright. We had a silverado, 2500 gas that we were concerned about so we traded for the diesel. We pick up the 3055 on wednesday and we will know more after that. I will let you know about the room around the sofa bed then too.
