I eventually bought 3/4 ton diesel pickup trucks to tow my RVs. While a lighter duty pickup will work at lower elevations and fairly flat terrain, one doesn´t have to spend long pulled over on the side of a mountain pass cooling down while cars and trucks pass at 70 mph plus to conclude that a far more powerful vehicle is worth every penny.

I am a big fan of 4 wheel drive. I rarely use it, but like Murphy´s law, it will always be needed at the worst possible moments and in the most dire circumstances. And, those diesel pickups in 2wd will get stuck on a wet lawn - literally, it happens at least twice a year.
