bed platform and engine compartment heat?

On my recent trip stopping in a warm climate for the night, I found my bed platform and bedding was very warm preventing me from using it for several hours. Anyone have any solutions to bleed the heat out of the engine compartment or insulation that would prevent engine heat from transferring upward into the above platform bed? On other forums, people seem to have a storage space under the bed to insulate but my bed platform has immediate access thru a panel to the engine compartment. The couch worked fine for those hours before bed area cooled. I suppose if it was 20 degrees outside, it wouldn't be a problem but outside was 80, even at 2100 that night.. I did do a search but couldn't find any info. I think this has been discussed before. If anyone has a link to that thread, feel free to post.. Thanks..

Two solutions, Mike! Salute
1. Do your traveling when it is colder and you will appreciate the warmer bed. Wink
2. Run the generator to power the roof air and turn the bedroom air to 45 degrees. Thumbs Up The bedroom can double for a meat locker also. Keep the bedroom door closed. cheers

roof air won't solve the heat problem coming from below... Do all pushers have just a thin panel separation between the bed platform and engine compartment? I mean its just a 3/4" piece of plywood being used as an entry port..covered with thin carpeting..

You will want some form of insulation on the engine side. Be sure there are no air gaps first.

My coach has some sort of foam material with a metallized skin, not sure how thick. I will investigate.

Sleep number bed with cooling mattress might work.
If you search Nick Cagle's posts, I think he insulated the engine compartment on a rig he had. I am not sure if it was a Barth. On the other hand if you insulate the engine compartment, would you need to provide extra cooling fans for the power plant? What was your engine temperature running at when you were driving the 3208 thru the mountains?

wasn't running hot, maybe 180 or so..Only short runs of uphill, mostly gentle grades to Flagstaff/Continental Divide at 7300'.. I usually leave it running for 5 minutes before I shut it down.. Maybe not moving allows heat to go only upward..just guessing.. I'll check Cagle's posts..

Advantage of a Breakaway, engine access from the bedroom.
Disadvantage of a Breakaway, engine access from the bedroom. If connected to shore power you might add a fan to the engine compartment with a temp/timer control. Save that option insulation is the only option. Rusty, I remember touring your coach but don't remember the insulation level under the bed, chime in.


Part 1: How do you fold a fitted sheet?
Part 2: Where do you look for socks if you don't have a fitted sheet in the dryer?

I would like to add a third and fourth solution to Kevin's argument

3. Trade in the rear engine diesel on a front engine gas or diesel
4. Find a spouse with very cold feet

My Regency's DD engine access was made of 3/4 inch plywood with at least 3/4 inch insulation with a reinforced edging.

Not sure what it was made off, however like Steve VW said the silver/metallic finish faced the engine, very little heat transmitted through into the bedroom.

Hi Mike: My Breakaway gets warm in the bedroom after a long drive when hot outside. My engine access is virtually the entire width and length of the bed, (short queen)but it is about 2 inches thick and HEAVY! I usually don't run the diesel long after stopping, just long enough for the EGT to drop below 300 degrees.

I have an insulated wall around the engine vertically as well. I have often thought about additional insulation for both noise (not bad) and heat.

I wouldn't trade a pusher for any reason.
