the upper cabinets are made in place, and actually screwed into where the top screws into the roof, I used many 1-1/2 self tappers to secure them to the old roof. they are also attached to the wood strips in the top too,with metal brackets . the bathroom is very small, but does the job in the smallest space I could use. I didnt use any 2Xs, the weight of the lightweight mdf is about 45lbs a sheet, and I used 5 sheets total which only comes to around 200 lbs if you figure all the curves and waste I had off every sheet, and I still have a half sheet left over..
yes, everything is glued and screwed, and with the fuzzy fabric covering, I get more joint strength .. I used LED self adhesive lighting. the wife and I have been sitting in there for many hrs planning the van finishing, with the lights on without any problems, they are the same LEDs that I use under all my custom kitchen cabinets. they also have a dimmer, and each section has its own switch to cut down power usage. I used a vinyl plank flooring on top of 1/2" plywood, on top of 1/2" foil insulation board.. the rest of those pics must still be on the old forum.
after filling all the tanks to calibrate them, the van didnt drop down at all, I figure I had about 500 plus lbs of water at one time. I was worried about weight seeing I put the 3"drain connector below the running boards, but I just measured it again yesterday, after I took it out for a drive… its still 8" from the bottom of the pipe to the ground.. I think the mdf was a great way to go now for weight savings.. the walls have 1/2 insulation board, and reflectix insulation. I used 1/4" plywood over all that. I used corrugated plastic sheets with foam and vinyl over them for the ceiling, just trying to keep the top lighter then the bottom of the van. we were going to use a cherry finish for the cabinets and doors, but we figure, paint is easy to touch up when something gets scratched… I hope I covered all the questions.. just ask if you need more info. I'm glad it could help someone… also, weight placement is very important in a van, it does its best with the heavy loads between the wheels, I've had 3 full pallets of floor tile in that van, and it barely moved with several thousand lbs of tools and shelving, but put a lot of weight past the center, and the rear will sag fast.

here is the floor, I use a commercial runner carpet over that, it makes the floor warmer when its 20 degs out. I put the floor down first, because I made the rear seating, and all the lower cabinets removable, if I needed to move something big, or get 20 sheets of plywood or drywall for work. I saved the cargo mat, and I'm going to also custom fit it around the bathroom and the sink if needed
