The drawers and doors will be inset as I want everything flush. Less of a chance of things getting banged up that way. I planned on installing cam style locks on every single door and drawer, keyed alike. The drawers will on be on Accuride 100 lb. full extension drawer slides. My thinking for the locks is this. I can unlock and pull the drawer out via the key to open the drawer. When parked on a street with the doors wide open, which is the way it is when you are working on a job, it's too easy for someone to simply reach in and grab something. This is a deterent and shouldn't be too much of a hassle for getting in a drawer.
Planning on screwing the backs of the cabinets to the 16" OC ribs that run vertically up the trailer walls. I'll run 3/4" horizontal stretchersacross the back, top and bottom to beef that up. 3/8" ply presently makes up the walls, but may remove it and beef it up a tad. They will also be screwed to the toe kick assembly.
I'm open to all ideas. My last trailer was a 6x10 and I outgrew it quickly. I vowed never to trip, stunble or hunt for anything again. My plan is to have everything in it's place and not a whole lot viewable by looking in.
Dave, planning on extending the back of the laminate on the countertop 1/2" or so and will scribe to the wall. Will inset the back panels 1/2" on the end cabs so I can scribe there also.
