Tonya is looking for something she can pull our 6X12 enclosed w and she's found a 11 Yukon Denali she likes.My experience w AWD is limited to the Mits Eclipses of the 90's that weren't exactly great.The trailer itself weighs 1700 ish empty and total weight would probably never be over 3K. Will the suspension hold up to towing or will it be problematic for the air ride/stabalitrac (sp???) they come with??? Whats everybodies thoughts/experience w the GM AWD systems???
