I accidentally towed about 30,000 pounds with my wife's half-ton Escalade once. Someone left the plug in the boat over winter and it was full to the gills. They said it'd hold 5000 gallons so I'm really only guessing the weight.

I didn't know it was full, I just went to move it and noticed the tires were flat (or I thought they were, they were just being crushed) and when I tried to get it going to the gas station to air them up, it was really tough to move. But when I couldn't get it -stopped- that's when I knew.

I pulled a 1/2 NPT gravity plug and let it drain for 2 hours, had lunch, then towed it home still draining all the way, but much lighter...

(I'm not bragging or recommending you do any of this, I made several obvious mistakes, just relating the story).

The Escalade had the power (430hp?) to pull it, but not the frame to manage it!
