Any of the vehicles mentioned will pull a 1000lb load. A Saturn with 4 college kids, tank of gas, and a trunk full of luggage headed to spring break is hauling close to 1000lb for fucks sake.
So your options are borrow a buddies 17 year old 150k mile blazer or buy someone's pos truck. Did you realize you could be fucking 700miles away from home when the used clapped out ranger/s10 breaks down?
Seriously take my cynicism with a grain of salt. I think you have a bad idea.
