I know that particular boat and when loaded as you would with gas, gear, drinks, coolers, fun stuff, and it's trailer, it's going to be
far heavier than a TJ should tow. Especially when you factor in its'
length which will create a long arm/moment (leverage) against the TJ's hitch ball which would give the boat and trailer too much control over the TJ. If you had an Unlimited, then yeah it'd be fine to tow but that's really just too much weight and leverage against the TJ to tow safely. At least in my strongest-possible opinion after 30+ years of towing lots of 17-20' boats behind lots of different kinds of vehicles. That boat and trailer would quickly teach you the meaning of the old phrase
'the tail wagging the dog'.
