Square Bodies, CUCVs, UA Tales, and Big-Rig Builds with Caleb Morrison & James Jenkins

Two builders who wheel hard join Overland Weekly to talk all things full-size: square body Chevys, CUCV military platforms, Sand Hollow and Moab magic, Unreal/Ultimate Adventure (UA) prep, and why “impractical on paper” is incredibly fun in real life. Host Davey sits down with Caleb Morrison and James Jenkins for deep dives on their rigs, the Full Size Invasion community, trip stories, lessons learned, and what’s next.

What you’ll hear:
- Why square bodies and CUCVs are still a killer platform
- Caleb’s single‑cab shorty square body on super duty 60/14-bolt, L92/4L80E, Magnum + NP205
- James’ crew cab square body with L92/TH400, 203/205 doubler, ORD links and Radflos
- UA selection, logistics, road days, miles, fuel math, and mindset
- Sand Hollow wheelbase sweet spots and why big trucks just “walk it”
- Full Size Invasion culture: camaraderie, trail fixes, and not leaving anyone behind
- Caleb buying Dave Chappelle’s UA‑proven “Louis Vieten” Super Duty and the smart mods he made
- James’ “Jolene” go‑fast rock crawler build (pinched front, clean fab, desert-ready)
- Hardest trails
- Rapid Fire: trail snacks, music, Milwaukee vs. DeWalt, favorite square body years
