Have the other partygoers follow in another vehicle if possible.
My payload allows 1 passenger when towing. Others meet us at the camp site.
I break the rule with Nana though (grandma). She weighs ~88lbs soaking wet.
Yes, a second passenger vehicle would free up some payload. Also, putting all the luggage and cargo in the trailer (as long as there is capacity there) instead of the tow vehicle, frees up some payload.
Say you have 200 lbs of luggage in the Yukon. All of that two hundred pounds, counts against your payload. If you put that 200 lbs in the trailer (close as possible to the axles, but, not behind them), only a small percentage (near 10 percent) would add to the tongue weight. Thus, you've freed up about 180 lbs of payload. Your tires will thank you for taking some of the load off.
You may still be on the edge with GVWR, and still have some unpleasant towing, but, maybe you can get some relief from the white knuckles and back aches, by trading off driver duties.
Original post, stated an assumed 1000 lb load of passengers and cargo. Maybe, that load can be reduced. Maybe, the assumption was a little high. Only the OP can figure that out.
