Towing to the track

Last weekend I borrowed a friends truck to tow my Duster to the track (approx 130 miles round trip) It's a 94 chev 4X4 with a 350 & auto. with my Duster on a U-haul car trailer, this thing was really struggling, & could do no better than 8 mpg. driving 60-65 mph. Anyway, I need to find a good strong truck to haul my car to the track, What do you guys suggest? because I'm on a tight budget I may end up getting a tow dolly, unbolting the driveline from the car isn't a big deal.Thanks for your input!
