Hello all, we have a 2004 suburban 1500(1/2 ton) with the 5.3L engine, 3:73 axle ratio, the factory tow package and about 96,000 miles with a towing capacity of 7400lbs. We are looking to tow a 31' 60...
Typical 1500 Suburbans are very close to max limits with just passengers and stuff on board. I had a Tahoe with essentially the same drive train and it was a struggle to just pull a 21 foot TT with me, wife and large dog on board. There is no way in heck you will be good towing that much trailer with that little vehicle.
