I dig the Westy kitchen unit! I wanted to gut my m1010 so bad and start over, but I was surprised how handy the bunk system has been working for me. I decided to just kind of modify my designs around it. The bottom storage is pretty good once I realized how to more efficiently pack it. Milk crates are a great deal! Does your truck still have the 208 transfer case? I have been having nothing but issues with mine. I'll drive the truck 2 hrs down the highway about 55 mph and find a puddle of red atf where I parked. I even put new seals and output pinions out of the transfer case. I guess just bad luck.
Does your air conditioning still work? I haven't really ever used mine or tested it, but I was contemplating the idea of making that additional storage that you could access from inside the truck. I think it wouldn't be too tough to do. Cut, rivet, and seal in some aluminum to replace perforated metal on the outside. Then make a door or access panel, maybe even a plastic boat one, on the inside. It would free up that big old area where that a/c junk is at and allow you to store stuff!
Keep it up. Eventually there will a group of us M1010 guys!
