I had a 2008? F350 Diesel, SRW, 4x4, crewcab, Lariat. I pulled a Cougar XLite 28SGS, no issues. Traded to a Montana HC. Discovered I was at payload up against Gvw, etc. The F350 only had a payload of 3267#. (That number is burned in my memory). I discovered Ford makes, made, several variations of the 350 with different ratings. I visited a Ram dealer and looked at the same equipped Ram with a 4016# payload. I'm on my second Ram 3500.
Maybe post all your numbers off the Ford yellow sticker and your weigh tickets, empty, and ready to travel with the camper.
