Re: Real World info needed! Suburban/Yukon Delanli XL??
6.2 are nice, but I have a ccsb gmc 4x4 with the 5.3, 6 speed, and 3.08 gears and normally pull a heavy 20 foot trailer usually loaded up with a square body chevy. It does just fine.
Its all about whether or not you want the power of a 6.2, or the mileage of the 5.3. either way you'll probably be happy.
