I was thinking like you until I found truck conversions about 2 years ago. Next week I take my Freightliner to Indiana to have a Show Hauler conversion added and I couldn't be more excited.
I actually am leaving tomorrow evening to Harrisburg, Pa for a RV show and will be taking my truck instead of my Ford Explorer Sport Trac. The truck rides so nice even without any weight on the chassis and much more stabile even in the wind.
