Posting this in case it might be of any help to someone else that might be thinking of installing a microwave
in their trailer,
After I had almost completely gutted my Trillium
at the end of 2012 I wanted to install a small microwave
in the cabinet above the existing fridge
as the first step in the reno. I had stripped this floor to ceiling cabinet down to it's bare bones and installed two new upper shelves, one for the microwave
to sit on and one right above where the microwave would be.
Microwaves have got a bit of weight
to them and I went through a few ideas about how to retain it on the shelf whilst travelling. I eventually came up with a simple solution. There are two little hard rubber feet at the front edge of the microwave that are only 3/16 - 1/4" high and so I made a strip of 3/16" ply with two holes in that match the feet on the microwave.
With this piece of ply fastened to the front edge of the shelf that the microwave sits on, the feet locate in the holes and stop it from moving front to back or sideways. The feet of course are too small to not 'hop' out of these holes while travelling and so when I apply the edging ( approx 3/8" thick maple ) to the shelf above the microwave I won't fasten it permanently in place. I'll put a strip of dense foam along its bottom edge and screw this edging into place on the shelf while pressing it down onto the microwave and thus preventing it from moving up and down.
The attached pictures show:
The cabinet in it's original condition.
The cabinet reworked with new shelves and inner surfaces of 1/8" stained maple ply.
U/s of microwave and the retainer ply with matching holes.

The shelf above the microwave that will have the 'hold down' edging fastened to it.
If anybody is interested I'll post some photos of the hold down edging and further finishing around this cabinet, maybe tomorrow,
