I'm looking to improve the insulation between the rear of the reefer and
the outside wall of Mellow Yellow. It can get pretty hot when in direct
sunlight. This bakes the rear of the reefer and greatly reduces the
ability of the refrigerant to remove heat from its interior.

Right now the reefer is pulled, its combustion chamber cleaned; its fins
cleaned; its mickey-mouse little fin-cooling fan removed and a larger
unit mounted (with JB Weld ); the fan's thermal switch removed,
thermally-conductive heatsink compound applied and then remounted; I
have removed the pressurized water inlet and mounted a waste heat
exhaust fan in its place; the now useless  pressurized water hose line
to the faucet removed and the fitting on the faucet sealed with a 1/2''
flanged cap.

There is presently a couple-three inches of fiberglass insulation on the
wall at the rear of the reefer cabinet.

I'm thinking to put some panels made of a cut-up windshield sunshade
between the reefer and the insulation --  to further block heat from the
rear of the reefer when the side of Mellow Yellow is in sunlight.

Does anyone have something better to recommend for this application?
