I've only towed with it once. My old Cole from Vegas to Kingman to store it for the Winter. Towed great, just never need it after that. I've always had a P/U, this is my wifes truck. I never launched with it so not sure how it does. Might be some other 2wd Tahoe owners here that can answer that.
MileAge, I would guess 14-16, my wife does all city driving.
Bump for a nice Tahoe.
I guess no one else tows with a 2-wheel drive Tahoe/Yukon
