You clearly don't care about your safety over bringing your toys.
I see people hauling one or two snow machines and or ATV's pulling a trailer almost everyday and I have never seen a broken axle/blow out or wreck caused by being a tad over manufacturers weights...
Heck, just go to the fiver forum or truck campers and you will see over the payload all the time or here my axles say it's okay to be over payload.
All the guy wants to do is haul one ATV in his truck and pull his camper..... I wouldn't hesitate to do it with his rig and I have been hauling an ATV in my truck pulling a trailer since I got my first ATV in 1988 with 3/4 ton truck with a GVWR of 7200 lbs.
Never an issue.
