While I have a nice 'payload sticker' (#1920) and the same GVWR as my Dad's 1971 F250 (#7700), I still have a pretty wimpy rear GAWR (#4050) and the #1,150 max tongue weight on the factory hitch would be limiting too...
This is with a 13 F150 "Max Tow" that has a "tow rating" of #11,500.. Which is the same "tow rating" as the HD Payload version which is #8200 GVWR up to 2014.
I tow a #5000 GVWR TT with it and I'm within #600 of going over the truck GVWR and even less on the rear axle.. The TT has around a #650 TW. I also load a lot of stuff in the bed as well.
For me, I'd go to around a #7500 GVWR TT with this truck and still feel it would be a very comfortable tow.
Yes, the "1/2 ton towable" label is very misleading and I wouldn't consider most of those branded RV's as such, but then I know what it's like to tow over loaded, and that's with 1/2 ton and 3/4 ton vehicles.... So, I'm pretty conservative in general when it comes to matching 'tow ratings' to 'tow weights' and 'towing comfort'..
I don't have any control over what others tow with their vehicles.. They got to the campground without dying, so I guess it works for them?
Anyway, looking forward to May when I can tow my TT again.. :)
