There have been a few discussion lately over towing with a B, so a thread on RV.net caught my eye.

The poster is contemplating towing right at max combined weight on a Airstream Avenue, cutting out as much stuff in the van as possible and putting them in the trailer to reduce tongue weight. He is talking a 6000+ pound trailer at this point.
I have only heard of one person towing that heavy that I remember, a guy on the Yahoo Roadtrek board, and he is a very experienced driver with lots of mods to the van to keep it cool (all fluids) and be able to stop it. We have all heard of the brake and heat issues of stock Chevies in the mountains and heat.
My guess is that he would be OK as a flatlander, but have some severe, maybe dangerous, issues in the mountains.
Has anybody towed anything that big with a Class B Chevy? Pickups will tow that easily, with the same engine, but they seem to be setup for it with much better cooling and brakes, and the truck weighs something like 4000# less.
