And I know your going to ask, I'm towing a 2015 Keystone Cougar 25rks 5er that weighs 6300lbs dry, 1125lbs pin weight. Its marketed as a "half ton towable 5th wheel" I'm only over some of my specs by 2 or 3%. It handles and stops just fine.
Your thoughts?
If your happy with the way the truck handles the trailer thats what counts.
Top safety priority is stay under the trucks gawrs especially rawr as its carrying most if not all the load in the bed. Rawr = the lessor of a wheel/tire/axle/or rear spring pack.
The F150 comes in several gvwrs up to 7850 and rawr from the tiny 3800 lb up to 4800 lbs for the HD package. One size don't fit all with Fords F150
I see many folks happily towing around 10k lb trailers with their F150HD 7850-8200 gvwr and 4800 rawr. These trucks can have 2400-2500 lb in the bed payloads....but in no way can compare with the F250 10000 lb gvwr and 6340 RAWR. That 6340 rawr can have over 3000 lbs of real world in the bed payloads. In fact the F250 with the camper package or heavy service package has the same suspension as the F350SRW.
1/2 ton vs a 3/4 ton = apples vs oranges when we look at the numbers that count.
