Not sure where you are located but Artemis Overland is in Springfield MO. They have great customer service and have a great selection of different items to choose from. Doesn't seem like this type of stuff has taken off in the true south enough to warrant anyone opening up a dedicated Overlanding Store.
Couldn’t agree more. Overlanding is a foreign concept in most of the south.
A lot of it kind of depends on your rig & your area. For example, I drive a Subaru & live in the upstate of South Carolina. Other than Asheville, NC where you can’t swing a dead cat w/o hitting 3 Subaru’s, they aren’t real popular in the southeast. The people who do, don’t really do anything off-road other than going from point a to point b on a pack gravel road. Because of that, I have to get most of my mechanical components through online retailers. There is a lot of off-road going on around here, just not a lot of overlanding. There are a few 4x4 shops in every town who are happy to throw on lifts & gear for both rock & mall crawlers - but those rigs go out to ride established 4x4 parks & then drive home. Most don’t plan on camping out, & definitely ever considered using their rig as a base camp. Other than REI & Cabelas where you can get RTT’s, baskets, & racks - there aren’t a whole lot of options for a physical store where you can get stuff.
However, if you are looking for gear for off-grid power, water, cooking & all the other stuff you need - check out a Camping World or whatever mega RV dealer you have around. Their stores are stocked w/ all that kind of stuff.
If you are near a large body of water - a big dealer that sells yachts, sailing cruisers, or deep sea boats (pretty much anything that floats and you can live out of) will also have that stuff. If you look around for some auctions at some of those places (or you can ask them where the local dry docks are) you can even get a deal on some second-hand stuff from decommissioned vessels before they go to the scrapyard or from craft that are being refitted for new gear. For long trips I have a compact electric range (oven/stove combo), a portable fridge, & a fresh water system w/ an electric intake pump, filtration, & tankless electric water heater that all run on a 12v system. I can fit all of it plus gear & 2 deep cycle AGM batteries with solar trickle chargers in the trunk of a Subaru Outback. Most of that stuff (except the pumps) were 15-20 years old, but they were pulled from a 65’ sailing catamaran. All of it in great condition but I only paid about 15% of what new stuff would have cost.
