A lot of people find out that the truck is overloaded, and they have to upgrade. At least you are smart enough to check the weights before putting down a (sometimes) non-refundable deposit.
You have to consider the hitch weight, all the kids, and what they will be in 8 years, before you are going to upgrade the truck or Yukon.
I do believe the dealer told you "You will be fine" towing anything they have on the lot. A LOT of dealers say that.
I don't know all about those vehicles, you can probably get the towing guide at a dealership for the GMC or Toyota and get a lot more information.

Money can't buy happiness but somehow it's more comfortable to cry in a
Porsche or Country Coach!
If there's a WILL, I want to be in it!
I havn't been everywhere, but it's on my list.
