Скачать или смотреть Homegrown 4X4 Van Conversions with The Swim Shop

In this episode, host Beau Wigington visits Justin and Seth Williams of SwimShop 4x4 to unpack how they convert GM G-Series vans into capable four-wheel-drive rigs, and the MIG welding habits that keep those projects rolling.

Key Topics Covered
Why van conversions? The rock-n-roll roots, “rolling living room” ethos, and first builds that sparked a business.
Unibody reality check: why G-Series vans aren’t body-on-frame, and what that changes in your fab plan.
The jig story: cutting a donor van’s underbody, flipping it, and welding it to a table to build 126+ kits consistently.
Bolt-on vs weld-on: using existing van holes, minimizing welds to two key pieces, and where welding is still essential.
MIG setup in the shop: clean metal, penetration, heat/wire adjustments, and why “don’t zoom in” can still be structurally sound.
Parts sourcing workflow: diffs, transfer cases, running gear—how junkyards and Marketplace make the puzzle come together.
Square-body compatibility: designing around ¾-ton Suburban geometry so catalog parts actually fit.
Working with family: keeping shared interests, sharing space, and growing a shop together.


Memorable Quotes
“We thought they had frames… then we realized it’s a unibody. Whole different animal.”
“We cut the van’s underbody out, flipped it, welded it to a table—that’s our jig.”
“Everything’s bolt-in using factory holes—only two pieces need welding.”
