We see a ton of Sprinter builds... I sold my loved 2008 Sprinter that I just remodeled and decided to build another on a new Transit. Ford Transit 147" High roof, Eco-boost. Here is Xplor 1. The new Xplor 2. first pulled the rubber floor and installed foam board between the ridges on the floor. taped it down.. installed insulated foil back close cell foam... used the mat to create a floor from 1/2 MDF. Extended the wood to the rear door 5" and added 3 inches to the step area... loaded the walls, roof, and wheel wells with Rockville foil backed butyl rubber. I install 50 square feet thus far, I have another 50 feet to install. Today I was building the horseshoe bed / dinette frame out of 80/20 1" black anodized aluminum. What you see here took 14 sticks 6' foot long of 80/20. I made most on the angle brackets myself. The system uses 1/4 3/4" carriage bolts in the slots. I bolted the structure to the factor metric rivet nuts using a L bracket. Installed rubber washer to control squeeks. Even had snow here in southern Louisiana !!! next up... Maxxfan install , cutting a hole in the roof. Yikes! Upper cabinets, kitchen, flooring, more insulation, electrical, fridge, sink, front seat spin around adapter plate, and wall / ceiling coverings. Why these door have all these holes? It looks bad and will need to be build some sort of trim. Also I will need to relocate the speaker.
