I need help choosing a truck to tow my new 5th-wheel. I am a first time owner of an RV and soon to be first time owner of a truck. My wife and I plan to travel the country in our 31 ft Colorado - 3 slide rv. It is listed as a GVWR of 12,192, Hitch-Wgt = 1844, Unloaded-Wgt = 9592. Any opinions on make, model, engine, rear â€¦ would be greatly appreciated. We are about to look at a Ram 3500SLT quad-cab 4x4; 6 cyl 5.9 cummings turbo diesel, 4-spd auto w/overdrive, short-bed with a pullrite, ride-rite air bags, and bilstein shocks all around. What do you think. Thanks in advance.
