6.2L engine, 2023 AT4X and I do have Timbren SES system on the rear. Car is a 3500# corvette, trailer curb weight they say is 2000#s. Truck is rated at 8700#s and 870 tongue weight. Tow distance is roughly 950 miles round trip all SE part of country MS, AL, GA then some mountain climbing last 20 miles of the trip. Not asking for mpg I know it will suck the gas at 65-70 mph. Just actual feedback on the total weight and truck handling it. I know that weight is in the neighborhood of some guys big bass boats they tow.
