P66: I agree with FTGuy about weight of 5er and size of toter. A fifth wheel trailer should have 20% of it's weight on the pin, for a 12.000# unit that is a little over a ton. You should check the tire rating max and the rear axle max in addition to the gross vehicle rating. Sounds like a nice heavy truck that is much better than some I see on the road pulling large heavy trailers. Good luck on the northbound trip, we have wanted to do that too. One state at a time I guess. ps: braking is not a problem till you really need it, ya got to have the brakes you need. Dave & Jenney
