PerryD -- there are middle-ground options between the 5.3 and a diesel. You could consider a newer Suburban or Yukon with the 6.2 and the 6-speed tranny. This gives a lot more horsepower, torque, and load capacity.
Ehhh not exactly... The 6.5L, yes. 6.2L, probably not. They didnt turbo the 6.2 making it a dog and a half.
Let's see, I've towed Airstreams with:
1995 5.7 L Suburban
1999 5.7 L Suburban
2003 5.3 L Suburban
2005 Duramax, and now
2007 Duramax
Why deny yourself any longer?. Just do it. Stay thirsty for power my friend.

Yes ... my comment about the 6.2 motor was a reference to the quite-high performance GM gas motors, a variation of which is used in the Corvette. In the Denali it is 403 hp and 417 torque. In round numbers this is about 100 more hp and torque than the current 5.3, and that is a difference you will definitely notice.
Looks like I just picked a whole bouquet of Oopsie Daisys...
I thought you meant the 6.2L diesel of yesteryear. Not much power, but reliability is there. As for the new 6.2L, a vast improvement over the old 6.2L diesel I thought we were talking about lol. Good mileage, good power, and should be reliable!
