Wrong forum for this question, but it will likely be moved to an appropriate one at some point..
Anyway, I tow a #5000 GVWR TT with a 13 F150 and I know it's back there... It can handle a bit more of course, but I would never tow a TT that comes close to what it's "tow rating" says... Which is #11,000... ha, ha...
I've been towing stuff since I was a teenager and that was back in the mid 70's, so I know what I like and what I don't like to tow. ;)
I can tell you that towing anything at the tow vehicles "max limit" is not going to be that much fun, but people do it all the time, so there you go..
Ultimately comes down to what YOU feel comfortable with and how much you want to go by the brochure numbers or what works for you in the end..
Good luck!
