I have a 95 GMC 2500 conversion van with the TBI 350 and tow package. Has the tall rear end gears, which is nice because I tow in '3' instead of 'D' to avoid excessive shifting/heat buildup.
It tows great with an 18' open trailer and ~3,500 of car/stuff on it, and offers better accomodations than a tent. It also serves as a nice nap/daiper changing space for my infant son.
As with any tow vehicle the transmission and brakes are the vulnerable points. I am adding an aftermarket trans cooler (in addition to the factory one) just to be safe, and running Performance Friction front brakes with general good brake maintenance (good fluid, annual flush-fill)
IMO these things are ideal for race weekends.
