I have to take a 300 mile trip with full vehicle 5 people and luggage plus some luccage and a few small furniture items . I have a drawbar hitch mount and a supplemental ATF cooler and have done some local utility trailer towing ( short runs to home depot etc ) . I was thing about renting a U-haul 5X8 cargo trailer for the tirp . Can my vehilce handlle it if I take it easy ( from Atlanta Ga to Fla Panhandle - not much in the ) . BTW I change the ATF every 12 kmiles ..
