I have a
2008 Suburban LTZ. It has the 5.3L with 4-speed tranny, heavy duty tow package, and 3.73 axle ratio. It is about to pass 36,000 miles (bye bye warranty). It's been a good family rig, but there have been a number of little warranty fixes (door locks, rattles, and the like), and I have never really thought it was a great two rig... seems pretty maxed out with my boat on long trips over mountain passes.
I have debated just selling it and getting a
2010 Yukon Denali XL. It has the 6.2L with 6-speed tranny which offers 93 extra HP amd 107 more ft-lbs. of torque. However, the axle ratio is only 3.42 and despite the extra power, the Denali has a slightly lower tow rating (7,900 vs. 8,000).
Getting a new warranty would be nice... but what I really want is a stronger tow vehicle. Would I even notice the difference? I'm afraid I'll get it out on my next long trip with the boat and it will act the same (struggle up grades and tranny fluid exceeding 230 degrees). Afterall, it's still a gasser.
Oh yeah... one more thing: the Denali XL would make my payment go up by $175/mo. If it's a vastly superior tow rig, that migh tbe worth it. But if not then it's basically the same vehicle that we already have.
Thoughts...?
P.S. Please don't tell me to get a diesel. This is my wife's daily driver and she won't go near them.
