Help Needed to pair new Tahoe w/ TT

Heres the issue really, while you may be within its limits you are at the upper limits which means you have absolutely no reserve to work with. Its an expensive mistake if you get a tow vehicle and find out that its not fun driving to where ever you are going...every truck that passes you will wiggle you around and you will be white knuckled all the way and exhausted when you arrive. Plus, I see you are in CA, you have big mountains and you need reserve power to get up the hills and lots of braking power going down the hills. Its expensive to correct if you find out you made the wrong choice.
