Let's just say you are weighing about 7800 lbs trip ready. You are looking at about 1100 lbs. of tongue weight.
Add that to the weight of all passengers(kids and dog), all gear in the Burb, the hitch, etc and see how it stacks up against the PAYLOAD you have available.
Probably close or over for a 1500 Burb.
Good luck with your search and decision. You are doing it right by researching and figuring before you buy.
