Jon Turgeons Fahrzeug (#1799)

We imported a 1988 Mercedes Benz 1120 AF into the USA for an expedition truck build. We have used a fiberglass/foam composite bow and other than the welding it is completely DIY. The build is currently not 100% finished. Things like the cab roof rack, entry grab bar, sand tracks mount, plumbing the second fuel tank and heating system install are left.

Floor plan

Explanation of floor plan
Optimized for a couple with seating forward and fixed queen bed aft. My wife and I have lived/sailed on a sailboat for the last 20 years. This truck is our new home as we recently completed a sailing trip around the world and decided we wanted to go around again, this time by land.


Material of furniture Honeycomb cored fiberglass skinned walls, maple/walnut furniture
All walls and furniture were built in place and Sika 252'd to the walls. The major interior bulkheads are 30mm fiberglass/honeycomb composite. The floor plan was designed so that as close as possible to the center there were floor to ceiling walls to support the roof panel and side walls. The edges of these panels were routed out and Sika'd to poplar cleats on the floor/walls and ceiling. So no visible aluminum extrusions in the corners. The counters are all solid surface LG HiMacs.
