Keeping fridge cool in high 90s temps

Thanks, all. I'd turn the rig if I could, but the little park we're in only has sites set up so that one side is to the east and the fridge slide out is to the west, so it gets the worst of the temps and sun. I'll go check Harbor Freight for one of those shade sails. It's got to be better than a piece of cardboard! The fridge was installed - I didn't do anything to modify it - and the door is one large piece with 3 rows of venting openings. But I'll speak to the tech guy in the AO and see if there's a fix he can recommend. Started putting the fridge on propane too, but as I said the compartment is too shallow to accommodate a fan. Thanks all!
