Thx for the information...
When I purchased the trailer (used from a private sale) the heat deflector was already there...someone must have heard of this idea
But now that I removed all the insulation on the sides, I am thinking this is my issue. I had the fridge running on propane for 2 days, and last night I put some cool beer in there as we were packing up to head out today. The morning, the beers were cold. I know a fridge works betters when it is full, so now it is loaded up, so i will see how it does this weekend...and when i get back, I think i will insulate it as it was before.
Just need to find a way to keep the mice out during the winter!!
Thx again for the ideas..
