I have a 2004 Mandalay 40D which has an air box between the air intake and the engine air filter.I recently had the RV serviced and they replaced the air filter.They failed to tighten the hose between the air box and the air filter and the box shifted down and ended up on top of the exhaust pipe.This caused the air box to melt onto the exhaust pipe. I was able to get it off and patch it, and secure it off the exhaust.In checking with Mandalay they said the air box was a plastic molded box and that the mold has been destroyed due to no orders in many years.Here are my questions:Do I need an air box ?Do you have one on your RV (my friends RV's do not, Tiffin and Monaco) ?If I really need one, can I even get something to replace the patched one I have ?Thanks

Ya, that is not a "wear component". So should be able to find one in a wrecking yard.Shoot pictures of it and do a search for "RV Salvage Yards". And, if you can find out who made it (Mandalay likely did NOT-- they bought it from someone) and the PN, you can find out who else bought that particular PN.Worse case, you can take it to a sheet metal fabricator and have a metal one made.

I have contacted a salvage yard in AZ, where members of the Mandalay group mentioned that there are a few salvage Mandalays.2Hands - please read the original post, I stated what Mandalay said.Brett - good idea as always, thanks for the idea, I will pursue it.CA Traveler - good idea as well, but i think I would like something a bit more flame and melting resistant.But the bigger questions for me is:Do I really need an air box ?It seems that it's sole purpose is to drain water out of the air intake system, when it rains.But many RV's don't have this box, so is it necessary ?Thanks

I completely understand that the issue at the end of the day is the need to locate the obsolete part or a replacement. However, have you made contact with the facility that serviced your unit? Clearly, if what you have said is accurate, they have a responsibility to locate the parts and make the repair at no charge to you.

Is repair out of the question?

PS, had a recall on our air box drain - hole was too small and would plug causing some real issues if the engine drew in water. I would say they are important.

MIle High, the melted portion is very large. Who could I take it to for a repair ?

UPDATE: No luck at any junkyard in AZ, IN, or MI. They had my RV but all the air boxes were melted from engine fires, so no luck.

Looks like I might have to fabricate one.
