Alot of tahoes and yukons have the 4.8 so watch out. Some have the 5.3, I think all 1500 suburban and Xls come with the 5.3. Your gonna want a SLT yukon/xl or a LT tahoe/suburban. All of them are available with 4wd so take your pick.
I wanted a short yukon, but got a hell of a deal on my xl. Now that I have the xl, I will never go back. But I also have 2 kids and it's the family hauler. I also use it as a truck as well, I have had the cargo area loaded down a bunch and I know some stuff I have put in wouldn't fit in a tahoe. I love being able to stick 4x8 sheets of wood in and still able to close all doors lol.
Also mine has the barn doors and I'll never go back to a liftgate.
