Older Reese hitch

The reese hitch is a good hitch but takes a bit of fine tuning. The brackets are not interchangeable. If you use the reese hitch invest in the anti sway that can be added to them easily. You did not give the wheelbases of he trucks and I would suggest using whichever truck has the longer wheelbase. You will still get some wag from the trailer as that length trailer will be marginal for either truck. We can hope that you did lots of homework on your payload capacity on the two trucks as that may or may not be an issue but not knowing the particulars it is impossible to make a determination. Check the yellow and white stickers on the door jamb of each truck as those numbers supersede any on line or brochure numbers. Good luck and keep us posted.
