I have 80k and the seat heater was a problem for awhile but mostly it's been in the shop at SJD and Vision Audio in Cameron, mo for upgrades. Pulling a 12klb trailer and thanks to timat SJD it pulls like nothings back there and Vision Audio in Cameron has put in a GPS JVC radio that gets me where we are going and now with the Denali retracting steps mounting and dismounting are way easier for this old Vet. Thanks guys. This weekend Rick Lance is putting on an intake bridge prototype so will let all know how it helps since we all know it will. IT'S BUILT BY RICK.
