Congrats on your new GX!

Disappointed you didn't include some pictures.

We'd live to see what you have and more pic's as you build it up!

The 150 is a great platform to build on. The only limitations would if there's enough space for whatever equipment and who all you plan on traveling with.
Some prefer a larger rig like the full size LC's, full size trucks or Sprinter vans.
The beauty of the GX is it's small enough to fit on Jeep trails, between tight spots, tight switchbacks, etc. I first overlander was a Ford F350 crewcab (8' bed). It had everything, 37" tires, 6" suspension, 15,000 lb winch, 3 air compressors, everything. But it didn't off road that will because of it's length and width. Open areas like desert, it was great! But when we got in the high country or tight trails, I couldn't go any further and had to turn back.
Below is the first overlander I built. I designed and built the entire over-the-shell rack myself. Sourced the snorkel from a Land Rover Defender because it had the same angles of the F 350 "A" pillar and the same side of the truck for the air cleaner. Took a long time to find that right snorkel.
