I have always had the best results and life with Fords. I always pulled anything I need with a F150 4x4 8 ft bed but I recently purchased a F250 4x4 8 ft bed and I would recommend you consider a 3/4 ton. The 1/2 ton will usually do it but the 3/4 ton will do it better and safer. My previous company had; Fords, Chevy/GMC's and Dodges. Over the past twenty years, the Fords gave by far the best service, followed by the Dodges, with the Chevy/GMC's last.
