You cannot tow something that large without a diesel dually super-cab and electric/hydraulic trailer brakes! OK, back to reality. I heard many of the same' problems' I could expect before trying to pull a 24' Albemarle with an ' 01 Tahoe. The transmission was always the weak link with that era 'Hoe', but mine had already been replaced, and a temp gage added to the cluster. Weights are well within design specs of the vehicle, the trailer properly set up, and speeds appropriate for conditions. I do not have anything more than moderate hills, and might not be as satisfied if I did. The 'Hoe does just fine, and behaves very well under heavy braking. I had to call GM to find a CGVWR for my vehicle, and discovered it wouldn't be hard to reach the 13k limit. The tow/haul changes only the shift points of the transmission, and the speed OD kicks in (60 for mine). And my cruise control is squirrelly. I cannot use OD without 'hunting', so I tow in 3rd. Your Yukon will be just fine, up to a certain weight and with a properly set up trailer, that is. Length is not much of a player, but effective trailer brakes is. Stability will be fine as long as your tongue weight is appropriate to the weight (and behavioral characteristics when underway). The first thing I would do is weigh the combo to include tongue weight, so you start from a position of real numbers and not guesses. Make sure your hitch isn't overloaded by trailer weight (most are 5000# limited). Keep your speeds appropriate for the 30' of stuff behind you, practice sharp stops somewhere other than a crowded highway so you know what to expect (and change/adjust). Do not encroach on weight limits, the best that can happen is nothing, everything else is not good. And if the vehicle seems to be laboring, it probably is ...
