Trailer or bigger truck
I wouldn't do a 5'r on a half ton. Even without looking at the numbers the payload isn't there unless it is a real small rig. Don't forget you need to add the weight of passengers, options and other stuff you are carrying as payload. Just this week I traded my 28 ft Jayco travel trailer in for a Sabre 32RCTS. I was pulling the trailer with an Expedition (basically a half ton). When searching for a truck for the 5'r I was a few hours away from pulling the trigger on a 3/4 ton F250 until I realized the Diesel engine ate up 500 lbs of payload leaving just over 2650 lbs. With a dry pin of close to 2000 lbs and the DW & I weighing in at about 310 and a 200 lb hitch, well it was too close for me. Would it have worked, I guess so, but I opted for a full 1 ton F-350 with a payload of 3750 lbs and glad I did.
