2016 Yukon/L680 Transmission upgrades for HD TOW 2016 Yukon XL
It's a gas motor so it's going to rev up if while towing. I'm new to gm's (just got our 15 suburban a couple of months ago, wife's vehicle so I rarely drive it) but from what I found the max torque is over 4k rpm and max hp is over 5k. Sorry if I missed it but I take it your rv is a non pop up...- 15burban
