Short answer, No.
Long answer, Syclone's came with a poor payload rating from the factory, like 500lbs.
The lowered suspension can't handle more than that, the trannies break with the power they make stock, let alone the added stress of towing. Towing would put the truck in boost a lot more, creating more heat and stress. It makes mad torque & power, and would be ok in that area, but I'm sure you've driven a turbo diesel towing truck...those will stay in boost for minutes, hours at a time possibly. Try that in a Syty and you'll be picking up parts down a mile or two stretch of road.
Reliable? HA! Sorry, no again. Trannies break, engines break when not running 100%, ignition system has to be watched like a hawk, they run hot, break heater cores like it's going out of style. Vacuum lines need to be watched as well, since the high underhood heat eats 'em. The turbo & wastegate are crappy, and you'll have boost control problems, which could lead to detonation & dead motor. If you can remedy these problems & live with them, and learn to understand the trucks at a basic level, you can finally then enjoy the trucks.
GM just didn't put the R&D into the trucks that they deserve. :evil:
