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?

 

[91RS]

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.

 

[bigdog9191999]

as many have stated your mechanic is full of it. as long as maintenance I good and everything up to date (steering tight, brakes good ect) hook that thing up! as long as things are in good order miles is nothing, condition and being properly set up is everything!

We did rent a huge tent trailer awhile back (and the owner kindly filled it with water before we went up a huge incline in AZ from Phoenix to Payson and on!!). Looks like the trailer was a bit heavier than what we're considering. I try to stay off I-15 as SLC drivers are crazy for speed and the road is ALWAYS under construction. Is the Sway Away item you're talking about in addition to the weight distributing hitch? Thanks.

Thanks. Always kept up with maintenance, fluids, etc. New brakes and tires a few months back. Looking good so far, but probably need new shocks first.

 

[avalonandl]

Get Bilstein shocks... You will thank me later. AVOID RANCHO...they ride harsh

We have a 2012 Yukon SLT 4x4 with the larger tow package. I added internal airbags to the springs, upgraded my transmission cooler, which absolutely helps in warmer climates, and have a larger weight distribution hitch with sway control bar. I have Falken Wildpeak AT3W load range E tires as well. My trailer is a double axle TT weighing around 5k loaded. The max trailer weight for my Yukon is 8400. I added the load range D trailer tires with a 87 mph speed rating so I can keep up with traffic. The 5.3 likes the higher rpm‘s while towing. The MPG however are between 7-10.

HAUL-MASTER

Trailer Sway Control Kit

(253)
$29.99
Simple to install, An absolute must IMO. I could write paragraphs on the pro's and con's of RV'ing. You might as well buy your travel trailer and join the club!

Hi Randy. I'm coming to this party a little late but I'm another happy camper with a 2011 4WD Suburban 1500 LTZ which I bought last year with 231,000 on the odometer and lots of maintenance records. My 17' Winnebago weighs in between 4000 and 4200 depending on the length of trip and my wife's packing, which is a bit lighter than your target but I can say I don't know it's back there unless I'm in a real crosswind. That said, I've put some serious effort into bulletproofing it, even with those receipts for history. As others have mentioned, that started with ditching the air shock system and installing Bilstein 5100s all around. I also replaced the 1000 lb rear springs with 1250 lb Moogs (pretty sure they are the Z-71 spec springs) and set the ride height in the front to match the increased height in the rear from the stiffer springs. It is a wife-approved upgrade and handles the trailer very well.

Up front, I replaced a leaking radiator with a 3" Cold Case aluminum radiator and upgraded the stock HD transmission oil cooler with a Tru-Cool 40k, which is a monster, and finally, a bigger battery when the one that came with the truck gave up the ghost. It goes without saying we changed out all the fluids - brake, oil, full transmission service, T-cases, and diffs. New plugs and wires. I'm running 32-ish inch tires on 18" wheels and am starting to wonder if maybe 3.73s might not be a good idea. I'm also going to keep an eye on my engine temps on a long trip this summer and if I don't like what I see I may switch out the Tru-Cool for a Derale with fans that can be located somewhere other than in front of the radiator. But I'm hoping the oversize two-row Cold Case keeps things under control. When I upgrade to lithium batteries in the trailer, I'll get a big Mechman 250 - 350 amp alternator, but that's a year or so down the road. There's a few other mods that pertain to not getting caught out in the wilderness without gas or air or such, but they don't impact towing ability (you can see them in my signature).

As far as a hitch system, our dealer installed a Husky WDH with 800-1200 lb bars that take care of both equalizing the ride height and controlling sway. I've used the Haul-Master system above - years ago my family pulled a 30 ft. Holiday Rambler with a 3/4 ton International Travelall all over the west - and that's all we had back in those days. My personal feeling is the new designs which incorporate anti-sway with the weight equalizing function are superior but they both work.

We're headed to Michigan's Upper Peninsula for three weeks this summer and hope to make a three+ week circle through Big Bend National Park, Carlsbad Caverns and Roswell in New Mexico, and back to Palo Duro Canyon from Chattanooga, hopefully as soon as this winter. We'll be packing 10 extra gallons of gas, 10 extra gallons of drinking water, plenty of tools, a big puncture repair kit for the tires and heading out without fear. No freeways at all - 2 lanes only. At 114K miles, yours is just getting broken in. Do the maintenance and the upgrades you think appropriate and go explore!

Ok, I like the read and enjoy hearing stories of the adventure and convenience of exploring/traveling with an RV.But to say "I dont even know it's back there unless im in a real crosswind" Is maybe "stretching it" a little? I get it, You like your rig and have made some real improvments but i promise i know from experience that if you are climbing "any" hill in excess of 5% you are at 3500 rpm or above and if you let off you will find yourself in 2nd for the remainder of the climb. It is the reality of the 5.3 and 342.

I hear you and I'm not arguing, but given that I first used a 2000 ZR-2 with the 262 ci V-6 to pull that trailer, I really don't feel much now. Talk about underpowered, undercooled, and underbraked...

While I don’t discount your bilstein shock upgrade, I wouldn’t be so quick to dismiss the factory air ride system. I don’t disagree that it has its limitations and it’s certainly known to fail. But I tow with the Z55 air ride suspension and absolutely love it. I love the auto level functionality, though I have added airlift helper bags in my rear coils for added level and stability. I have replaced my factory stuff with arnott suspension components and compressor but it all works quite well when I tow.
