Towing Speed - Am I Going Too Slow?!

While a Burb may be designed as a TV, it will not have the same stability stock as 2500 PU, due being designed to also provide reasonable comfort to passengers. The springs and shocks with both be a bit softer.

Correct as far as the 1500 Burb, it has coil springs and is a better people mover than a tow vehicle. NOT true for the 2500 Burb, it shares the same leaf springs and torsion bars in its suspension as the 2500 HD pickups. The ride comfort in the big-block burbs comes from the AutoRide Real Time Damping system that uses shocks with magnetic fluid to vary the viscosity and provide a less bouncy ride.

Where the pickups add stability is not through the frame, suspension, or drive train, it's through wheel base. At 130", the burb is basically a reg cab long bed truck. Add ext cab or crew cab to the long bed and you have a longer, more stable tow platform. I compensate for a shorter WB by using a Hensley Arrow to better control the trailer. While I've never driven my trailer out of a ditch on 2 wheels, I have done some heart-stopping evasive maneuvers and I don't think I am lacking anything in the stability dept. I can run through a slalom just as fast as any 5er.

To the OP, you should get the truck weighed if you stop for gas at a truck stop. With 2 adults, 2 growing teenagers, the 3rd row seat and some stuff in the back I scaled in 8700 lbs against a GVWR of 8600 lbs., or course that was with the 34' TT. The 8.1 is drive by wire so performance isn't really a good indicator or weight....I'm not saying this to be critical, the burb will run all day with a full load.

Also, 2nd gear will hold you to 55 mph max on a steep downhill. 1st will let you run till 40. Only thing I wish they could have somehow figured out how to get the Allison transmission in these trucks....
