Using an angle grinder and cutoff wheel, the rear bumper gets notched to accommodate the main deck supports -- 2" x 2" x 3/16" thick angle iron. These are bolted to the chassis rails using 1/2", Grade 8 nuts & bolts.

Shot of angle iron attachment to chassis rail. The angle iron members are 4' long.

The cross-members and end pieces are 2" x 2" x 1/8" thick angle iron, 6' and 18" in length respectively. We drilled and bolted them together while they were clamped in place.

The deck depth is 18", but the expanded sheet metal we intended to use for the floor was 24" wide...so we used the sheet metal brake to fold it to size.

The completed project, 6' wide and 18" deep.

Another angle.

2 sets of cabinet doors. The fridge is also permanently installed, with a dry-erase board front panel.

(After running out of the oil-based paint we'd used for front of the counter/sink unit...we switched to a latex-based, almond-colored paint for the pantry. It turned out greyish so we'll go back over it with the original paint.)

Shower rod installed and finished lower front of tub with FRP.

Finished paneling around the front door.
