Bob,
When you say chimney effect is it just a matter of installing a fan that will draw hot air out through the upper part of the out side grill? I would love to see a pic of a properly installed exhaust fan.....Anyone

Check out this PDF from the Norcold site...

Proper baffles are more important than the fan itself, IMO. The fan install depends a bit on the fan used. I'll see if I can find some pics.

Should this part of the thread be moved to a seperate fridge fan thread? I think I've cluttered up the options thread a bit...sorry 'bout that!

Bob,

Welcome to the board and thanks for following up with the information regarding proper fire resistant materials and maintaining proper clearances and ventilation around the rear works. I based my work on the construction details provided by Norcold in the installation instructions to completely isolate the frig box from the works while maintaining proper ventilation and air flow for both the exhaust stack and the cooling fin tubes. I sure do recommend that anyone reworking their frig study the factory instructions carefully before the start.

My Ranger has the Dometic RM2193 fridge. FWIW, here is the installation manual for it

I'll add two ideas to the good ones of the vent stack fan (they can be thermostatically controlled), the inside distribution fan, being sure the reefer was properly installed w/regard to venting and insulation, and running in LP mode (moves more BTU's than 120VAC, which moves more than 12VDC in most reefers; check your specs).

If possible, put some kind of flexible, see-thru material across the bottom half or two-thirds of the reefer front inside -- The objective is to keep the cold air from 'falling out' when the door is opened. If the door is being opened a lot for drinks, consider a cooler and ice for those.

We can put the other vent in anytime you would like if you are up in the area. Changing the head liner would be a bit of a chore. I apologize about that one. Should have said something when you picked out all the other fabric for the camper. Just never thought of that one, never had a customer want to change it on us before.

Hey Ben,

Are you back or are you still out on the road? Good to hear from you again

I made it back Saturday morning. 11 days and 4100 miles later. Stayed with my daughter for 3 days and took care of some business in Oklahoma for a couple of those days. Playing catch up now. Looks like about 2 more days to answer everybody and get things back to normal.
