Anyone using an GMC AT4 or any other GM pickup for overlanding?

[landis76]

I just made the transition from a Jeep JKU to a 2020 GMC AT4 and finding that outfitting options are a little more difficult to find more than I thought over the Jeep. Yeah I know, "Duh" but I had hope to find close to as many options as I would find for Ford or Dodge.
Side question: Has anyone found a hard tonneau cover and RTT rack combo that works well together?

I have 21 AT4 not a real overlander but I use it for plenty ,i have a Bak x4 cover and have been looking for a rack. found some nice ones but they are pricey

Nice truck, I like the At4 a lot.

If you're on IG you should be able to find a few AT4 overland rigs. How similar is the bed to a chevy? Maybe they work together?

I think one of the contributing writers here has one.

my buddy loves his diamond back. he is going to run it with his james baroud XXL. I am expecting AEV to come out with some stuff for the at4's as there has been a couple of AT4's with mfg plates at the r&d for a long time.

I was thinking the same thing - looks like an ExPo Project Truck:

Expedition Portal Project :: 2021 GMC AT4 Diesel - Expedition Portal

There is no question that full-size trucks are becoming the new vehicle of choice for North American overland travel, offering robust payload and towing capabilities. Most of the reason for this shift is the generally anemic mid-sized offerings, some providing less payload than a sedan. The...

Of note - the front bumper situation is a bit of an annoyance, and GM has gone through quite a few "face" changes in their trucks. I had a difficult time finding a proper Bullbar for my Canyon that I trusted and ended up getting an ARB one for a Colorado; the nature of the GM marque is there seems to be a lot more stuff for Chevys than there are for GMCs. I'm not sure if the same "borrow it from a Chevy" approach could be done on the AT4 Sierra with a Silverado bumper. The frames are the same but the front fascia is different enough that cross-fitment is not guaranteed.

don't know if it would fit but I helped install my buddies Warn bumper and it is a quality set up and after seeing the stock bumper which feels like it was made from a recycled six pack of aluminum cans I think a bumper on one of these is a requirement.

That looks really good, @jadmt and is a good illustration of what I was talking about. I’m not sure that bumper would mount up to the GMC version - the front fascia is a lot different and might make it hard to do. But, it looks like Warn do make a bumper for the GMC so there may be a lot more options than I thought!

I have a 2022 Silverado 1500 for an everything truck. I have already done some off-roading adventures in it.

I recently purchased a Retrax Pro XR hard cover as its secure, weatherproof, and versatile.

I know based on the previous picture that truck is silver. But in that light it looks like the old GMT-800 pewter. Too bad they don't offer that color cause it would look good on that truck!

I believe you're referring to Greystone Metallic

You don’t see many current gen gm trucks in these forums, personally I feel ram and ford offer better options. Plus gm has a really odd looking truck in the hd series.

I’ve set up my Colorado ZR2 Bison with a Retrax Pro XR tonneau and a Frontrunner bedrack to which I mount an RTT at times. Theft and bear proof. Even ran indoor plumbing for my wife (see downspout in photo #1). We lived out of this for about 6 weeks this summer while moving cross-country.

Just picked up the camper and really amazed at the build quality. Jay and the rest of the folks there really take pride in their product. Future plans are a basic 12V system and insulation.

This is the exact set up I am looking to achieve if I go with a RTT in the future. Looks great!
