Latest and greatest update:
After moving from Alaska to Virginia, I've learned I have more time and space to work on my little trailer. Thanks to the guys on this forum and on IH8MUD for some great ideas for a galley. I finally constructed my M101A2 tailgate kitchen using birch plywood, some industrial drawer guides, and lots of screws and glue. Basically, I have a flat drawer on the far left that will accomodate a small Engel fridge (yet to be purchased). Then, I have my gas stove on a bottom drawer in the center unit, with two other drawers to hold a myriad of food, cookware, etc. The center unit drawers are all 48-inches deep with 36-inch drawer glides. That takes the center unit to about midway between the wheel wells. On the far right, I have a small drawer unit. Both that small drawer unit and the fridge box are about 24-inches deep and butt up against the wheel well. The left, center, and right boxes are independently constructed to make removal/install easier, but the plan is to bolt them together and to the trailer floor.
The final touch was to add some aluminum 3/4 x 3/4 pieces to protect the rough edge of the plywood from future damage. I think it gives a nice finishing touch as well.
Hopefully, the attached pictures really are worth a thousand words.
Overall, this has been a great project and was fantastic practice for building similar boxes in the back of my Land Cruiser and F350. My mind is definitely working overtime coming up with the plans for those vehicles.
