Many of the store microwaves can be "cabinet mounted" but require a kit. The kit will fill in the hole and allow for ventalation as well as secure the unit in place. This may require a more expensive microwave, but save you from having to make brackets.
I installed a microwave in my 68 GT. Fit it nice and tight into the cabinet. I made my own trim kit. I placed it on a sturdy shelf and used a couple of L Brackets to secure it. Bracket screwed to side of cabinet, remove a screw form the microwave cabinet and attached the bracket. I used only existing screws as was somewhat afraid to drill into the cabinet. The unit has rear and side vents, I have a lot of clearance around the unit. I believe yours is a 84. The new units are much smaller so you should have more than enough room for venting.
On venting I have a large muffin fan mounted under my cabinets which pushes air over the Refer coils and up the Refer vent. Helps a lot, wired to run when ever the trailer is on shore power. This also vents the microwave. BTW I have the same setup on my boat except in addition to the brackets I have a copper bar which is place across the front of the unit when uderway, nothing like a microwave flying across a cabin in heavy weather.
My wife works for Macy*s so we purchased a small Sharp Microwave, well under a $100.00. Figured if it lasted a year good enough. I belvie the unit on the boat is also a Sharp, it gets very hard use and has held up fine.
