You are so welcome,
yes I tred a small fan sold for behind the fridge, it was less than efective it came with a thermocouple switch that never worked for me. It was later I found on the airforums a wiring diagram showing how to wire a switch to give a hi-low-off option with silent computer fans 12v
. Thanks Airforums! The back of the fridg was to tight to mount them so that is when I installed them in the roof vent cap area. The fans pulls air across the coils in lue of blowing across the coils. And the copper hood stops the hot coil air from entering the cabin pulling from the bottom of the fridge, the in side cabin air is used, and the sevice door is not louvered but when out side temps are lower I open the service door and prop it open or closed if the outside air is hotter than the inside air.
I know that the the venting of hot air to the cabin was unacceptable for us on our first trip in May in Missouri, hot and humid. In regards to AC and roof vents controlling the heat gain from the fridge coils, first AC means no Boondocking you must have shore power, and the build up of heat while traveling down the road to your next location, you may find yourself saying I wish I had. And the Fantastic Fan is was not enough for us.
The wife and i have spent time in Agusta, MO. The wife partisapates in the spring Arts, she will be there after the Rally in June. I sell jewelery to Robins Nest there in Defiance, MO
And shame on you for saying "if we have to replace the M50"
that is a piece of history that we are so proud of and as you may have sene on our blog, she was brought back to life hopefully to serve another 50 years of good times!
Would love to see some pics of your Baby!
If your in KC area sometime give me a shout, love to give you a tour of our Babe.
Rallys are not for all, but a great way to meet folks with like minds. And great ideas.
PS anything you do to move air across the coil is better than what was IMO.
Good luck. Save travels.
