Start Towing with 114K miles on my Yukon?

[Blk 09 LTZ]

So you’re clear on connecting the hot wire under the hood to get power to the inside of your trailer? This connection is not to power the trailer running lights, but to power things inside your trailer and charge your auxiliary battery while you’re traveling. The wire is coiled up near all the wires by the brake cylinder, mine is red with a black stripe. It needs to be attached to the right side of two hot terminals at the front of the fuse box. The other terminal is for a brake controller connection. Just FYI

Thanks! Very Helpful. I may need a pro to help as I have a 2nd battery running a Dometic Refrigerator/Freezer in the back of the Yukon and I'd want to make sure I'm not messing with that at the same time. I appreciate the photo. Someone mentioned the trailer brake controller not being hooked up from the factory. I'm assuming that's what goes to the other terminal you mention.

The factory trailer brake controller is hooked up and ready to go. If the vehicle does not have JL1, there's a bundle of wires under the dash and the one between the fender and fuse box are all for an aftermarket controller.

This was in October last year when she was shrink wrapped and ready to head down to winter storage in Orange County CA. It’s about a two hour trip down a good size mountain. Lol. Denali handles it no problem.

We’re actually headed back home with our tow setup which is similar to yours. It’s a 22’ with a max weight of 4,800 pounds. Our suburban is a 12 with the factory tow package as well but I swapped in some 4.11 gears after pulling it one time with the 3.42 factory setup. So far the factory cooler has worked great but it’s also cooler this time of the year so I plan on swapping in a bigger cooler as well. We’ve been all the way up to New York and wouldn’t try it without the 4.11’s for our setup as we have 33X12.50 tires. With the 3.42’s around the house it stayed right at 3k rpm. With the 4.11’s it does great at 2,500 rpm.

edit: that’s at 65 mph. And 103k miles on it.

Looks great. The trailer we're considering looks very similar but has 2 axles. I have oversized KO2's on the Yukon. Yours looks like it may have a lift?

I tow with my 12 at 187k miles when I need to. No idea what the previous owners did. I also don’t drive like a jack wagon clogging up the road either, I keep up with traffic.

Just my 02, First you are a short wheelbase which is not "optimal" for towing so just as important as the weight distribution is a "sway away " device. Also as mentioned earlier get ready to see a "minimum" of 3300 rpm when climbing. I would advise renting your choice of trailer and taking a road trip to utah ie' 75 mph speed limit on the I15. Find out what it is like before buying a TT.
