Going with Rancho RS7MT (linear piston) They also have a 15% off right now. Similar to Blistein 5100 (digressive piston) but a little softer. Either mono tube will be better than the stock AT4 Rancho twin tube. If I run across any DSSV takes offs at a deal, I would love to try them.

Going with Rancho RS7MT (linear piston) They also have a 15% off right now. Similar to Blistein 5100 (digressive piston) but a little softer. Either mono tube will be better than the stock AT4 Rancho twin tube. But all depends on what your usage is…

I have used the bleach-white spray and also never use tire gloss/shine.

I do appreciate it the offer, but happenstance I have a second spare rim already. I also like the XOverland (Lifestyle Overland is another good one) and I think they’re going to Africa soon, which is going to be great to watch. Watching those is what convinced my wife to agree to the trip. In addition to the factory Jack, which I don’t expect much out of I do have a good bottle jack and I’ve seen people just use the traction boards for base plates that work fairly well… but what you have sounds interesting to. We went to Rocky Mountains including Winter Park and Mesa Verde a few weeks ago as a sort of test run and truck did great (I did use some extra seat cushioning for lower back).

OK so I did buy a scanner and download the wiring schematics along with a couple more items listed above so thank everyone so much. Also, expecting fine particulate dust (better than the alternative slick roads if wet), looking to do an EVAP canister filter relocation to under the hood before leaving. Basically just 5/8 hose some zip ties and a 5/8 push-in no-oil breather filter (Uni-filter UP124). This is why: and I know I don’t have a Yukon/Tahoe so it’s before the rear wheel, but this also helps explain it:

Just make sure it’s not cut, because if so, that’s the first thing thieves do before breaking into it…then comes the CANinjection override.

Sorry for all the post….but trying to be helpful. Did the zip tie trick and all worked great.

Also added an extra grounding strap due to this:

Also as extra insurance for some longer trips I have soon, I bought a used alternator from eBay from a crashed truck with 20k miles in great shape for $85 because I could not find any reasonable ones from GM. Normally I would just bring some extra brushes and regulator…but for under $100 bucks I am getting too old for that. Now changing the alternator requires a T15 to move the electric radiator fan out the way to.

Same issue. Have to also look at newer part numbers that replaced the one that came on the vehicle. Replaced my OEM 55581830 with 12720530. Reused a washer from the factory one just to keep it the exact same…May have been ok without switching it. To remove the belt I just loosened the idler bolt and used a screw driver (any tool with smooth leverage would work) and turned the engine by hand clockwise. Always disconnect battery before doing this.

Tires are #1 as chains should be rare. The V bar chains I like to use cannot be used with the factory 20 inch wheel. Currently using 1/4” spacers and front tire cables (Peerless Auto-Trac #0232810) factory tires is no rub (I’ll post some pictures). Going one size taller to 275/65/r20 (size on 2500hd trucks) in Baja Boss A/T very soon and should still be ok as same width. https://www.walmart.com/ip/Peerless-Chain-Auto-Trac-Light-Truck-SUV-Tire-Chains-0232810/54987986

Great information exactly what I was looking for. Thank you. I do have to strap and shackles along with tire and windshield repair kits. Good point on the water, taking two 5-gallon and a few 1-gallon potable already but did not even consider them as coolant so will make sure they are topped off more often. Will look into getting a portable Ham (did not even know these were available). Thanks again for the good information.

Thank you. Yea researched a lot online and just from experience, looking for anything that may be common on our trucks. Anything I can fix or take extra. Someone sent me this below which is a great idea to improve beforehand: Here is a picture of what mine looks like currently from the factory.

Planning a 9k mile round trip from Southeast Louisiana to Tuktoyaktuk via the Dempster Highway. Going with just the wife and no kids on this one…which is rare, but for 25th anniversary. Looking to arrive at the Arctic ocean sign in mid-late September (yes it is a long time away but a trip like this takes a lot of prep so starting now). Hoping to avoid the mosquitos and have a look at the northern lights. Truck is a 2019 AT4 6.2 with 75k miles. Have a budget and not looking to go all-out overland with rooftop tent or pull behind trailer. Looking for any useful advice from the forum please. Things already done to the truck: - added additional leaf spring (raised rear 1/2”) - added 1/4” front spacer to raise front 1/2” - added “Bambi mode” for all front lights (high, low, fog, tasks) to activate at the same time for high/brights. The AT4 (and Denali) comes with the Brighter HID LEDs and combined with this mode is plenty bright for my needs. May still bring a 12v magnetic spotlight just incase. - added leer 100XL camper shell/topper - sealed tailgate (both), inner bed, and additional on camper shell (dust on Dempster is crazy) and added blackout curtains. - added Rancho RS7MT suspension (dont expect to be loaded down enough for Bilstein/Fox/King), and worried about the washboard and deep potholes. - v-bar ice/snow tire chains and skinner Pieerless Auto-Trac chains as extras - upgraded battery to H8 AGM and keep assortment of extra fuses already Future: - researching tires but leaning towards Mickey Thompson Baja Boss A/T or Goodyear Duratrac RT-LT (both tires are 3-ply sidewalls) in 275/65/20 that will leave enough room with the 1/4” wheel spacers I already have for tire chains. Replacing spare under truck with Milestar Patagonia X/T 275/80/17. - thinking about having a 2nd spare on a hitch mount, but not sure if needed. Unsure if I want to use traditional wheel weights or high-quality tire beads so any feedback would be appreciated. - adding front and rear larger mud guards (thinking bushwacker) Related truck items: - installed plug-in on camper shell for plug-in camping spots already - (already use bed plug to power separately when traveling) 350 watt infrared panel heater, presto portable slow cooker, portable kettle for coffee/tea, portable freezer/cooler, and may bring heated blanket - have NOCO XL jump box and 12V All-top 12.35 air compressor - rodent repellent to place around vehicle when parked overnight (seen where this was an issue with electrical damage) - already have traction boards, hitch D-ring, HD tow strap/lanyard and shackles. No winch - CB radio and satellite communicator and dash cam, downloading Google maps offline and may get another…but it is not like there are a lot of roads to get lost on in the NW territories - changing all fluids and taking extra fluids, air filter, tire repair (plug and patch) kit, windshield repair kit, bottle jack and 4-way, general tool kit including electrical repair, gorilla tape, serpentine belt and pulley (zip ties to put it on). - instead of Jerry cans for extra fuel (since I won’t have a place to put them safely as no roof rack planned), thinking about a couple of the 5-gallon ethanol free fuel from Home Depot or VP fuel and a new funnel. Worried about the distance between fuel stations with a smallish fuel tank with lowered tire pressure and little bit of extra weight. Thanks in advance.

Well… seems like every year and a half I have to take it to the dealer to get rear window leak fixed. Noticed leak #3 this morning. 69k miles so GM does not cover and pretty sure the extended warranty will squirm their way out of it to. I used to buy (not lease) a new Denali (1500 or 2500 and Yukon) every 2 years but after a nightmare with the last Yukon Denali my wife would not buy GM so she went with Mercedes GLS and been extremely happy. With this leak (among a few other items), I will be switching to… was a life long GMC customer since 1998….
