Foam peanuts used as insulation?

I was checking out my new-to-me rig yesterday ('07 Coachmen Mirada) and found the space under the bedside drawers (no-slide unit) was full of foam peanuts. Underneath this area would be the full-width pass through basement which you see in some longer Class Cs)


Then I went to check the water pump location (was working but not pumping due to the Coachmen's manual water diverter system set incorrectly). The pump and fresh water tank is located under the bed (so no storage here). Again, the space was full of foam peanuts.



Is there any reason for this? Certainly not for packing fragile items. Can't imagine it does much for sound or thermal insulation?

I have not heard of styrofoam peanuts used in an rv for insulation, but they are good insulators as well as shock absorbing material. Styrofoam itself is loaded with air bubbles which trap heat and reduce transfer of heat. Think of styrofoam coolers and insulation for cold items. The peanuts are also an effective sound absorber due to the air spaces within and among the peanuts. However, loose peanuts may lose some of that thermal insulation if they are allowed to vibrate and separate, opening a "path" for heat to move between them.

In short, peanuts will insulate the spaces you describe if they are packed in tightly and secured. It seems to be a cheaper way to achieve insulation than cutting and fitting blocks of the same material.

Thanks. Peanuts are loosely-packed so can't think of what insulation value they have. Wonder if they were put there by one of the first two owners and if it will serve me better to get rid of them.

I'd get out the shop vac and suck them all out. They can only serve to provide safe harbor for mold and other detritus. If smothering the water pump the motor is overheating on extended runs.

I would remove them as well. I used to save boxes with peanuts for selling things on ebay later on and I can tell you for sure that most of them will degrade and shrivel up with time (~6mos to 1 year was my experience), start getting stinky, again with time, and some can get gooey sticky as well with time. Best to throw them away... imo. ~CA

Ditto on taking them out, I would rather have the storage space, you can always add dyna mat insulation if you notice a difference.

Insulation stops the movement of air, which then stops the movement of heat/cold. Peanuts can't do that, as there are air spaces around them, no matter how tightly you pack them in. Get rid of them.

Sometime lie down in a bag of foam peanuts. Though not as good as rigid foam, they do provide some R-value. The key, of course, is air movement. If air is blasting through them, then the R-value denigrates accordingly. But, if their presence is a physical liability, sure, suck them out.

I can't imagine the factory putting those in there! I would remove them and put in some other type of insulation. JMHO

Maybe they were left by foam squirrels?

Undoubtedly factory installed. I consider the brand.
