I added a few photos to my album.
The rig is a 2003 E250 RB40ish 5.4L V8. It has almost everything I wanted - walk through layout, Suburban propane heater, Atwood water heater, Norcold fridge, propane stove.
I say RB40ish because Wheelie (the second owner) removed the rear vanity/shower and closet, which left open the storage space in the back. This layout is ideal for me as it gives me room to store my snowboarding, kiteboarding, and mountain biking gear when needed.
Wheelie vinyl wrapped the original wood interior, and added a bunch of goodies including the Yakima rack, Bluetooth radio with rear facing camera, and new all terrain tires with alloy American racing rims. My near term projects include adding solar, a shower using the original plumbing, and (maybe) an underfloor storage box.
