Engine insulation

[RandyB]

There are several thermal barriers out there. A lot in the auto/motorcycle racing world. There are self-adhesive panels by a number of names and manufacturers. here's an example:

Well if you can deflect most of the heat before it get into the living area would be ideal. You can buy some after market insulation blankets for engine compartments. Here are a few I googled.

Thanks...we ordered a roll online. The original insulation above the engine is threadbare.

My Winnie was a 95 Gas Class A, the bed got hot on any trip. I found that the heater under the bed was the problem.

Mine is a diesel. What kind of heater under the bed? It would not have been engine related as you had a gas engine. My diesel is directly under the bed but my engine checks out to be running clean and not overheating.

Mine had a engine water heater under the bed for a heater in the bedroom while under way. At first I thought the engine heat was heating the floor but realized the basement would have been the only space heated and the water tank was under the bed in the basement. The valve for that heater was the culprit. The problem was the several hours it took for the bed to cool down made sleeping impossible.

If traveling in a hot climate, I run the generator and the house AC’s while moving down the road. Always try to stay ahead of the heat.

We had a rule of thumb that when the temperature outside reached between 93 and 95° we had to turn on the house AC. However, we also hung curtains between the cab and the rest of the RV so that the cab AC wasn’t trying to cool the entire motorhome. if we did turn on the house AC we open the curtains. (It took a bit of rigging – I ordered an extra long tension rod from Amazon and supported it on something, and it took three shower curtains. We used black because it looked more elegant and it was actually very nice for an extra layer of privacy. We’re shopping for another motorhome and I’m not sure, but they might be already including those drapes in some models? If not, they certainly should.

So, from what I’m reading all motorhomes are hot inside while traveling in hot weather ?

Yesssssssss, I think houses are the same way? ? Anything aboveground will get hot inside in hot weather.
Although Rvs are not as well insulated as most houses, they are considerably smaller in square feet, and easy to heat or cool. We had trouble keeping the cab cool, while traveling, in temperatures above 95 ..even with the little windshield fans going...So we opened the dividing curtains separating the cab from the rest of the RV, fired up the generator, waited 20-30 minutes for it to “make a field”, and turned on the house AC. Sometimes the temperatures hit the 100s even in September. With the house AC going, we were quite comfortable.

We have a 2000 Winnebago Ultimate Freedom. The bedroom area gets extremely hot while driving. We know that the engine area needs new insulation but we are unsure what to use. Please advise as to the most efficient material to block engine heat from entering bedroom area.
Thank you very much.

We had a 2006 Winnebago Journey 36G... Bought it when it was six years old and sold it when it was 12 years old. Never had trouble with heat in the bedroom.

Was it a diesel pusher?
