Foam Insulation Under Cab for heat??
Hello Campers! Took my RV to a local HIGHLY recommended shop to get their opinion about the poor airflow in my 2007 Ford E450 Winnie Outlook. He said that he has seen rigs come in with Spray Insulatio...

I already had Dynamat installed behind the doghouse and under the footboard and mostly under the chairs. It did help alot but I still have significant heat coming up by my foot and under the floorboard, under the chairs, turning my cab into an oven on hot days. The doghouse has been checked and is sealed properly. We do run the mix air once in a while but as most would understand, you don't want to run your air alot when the engine is pulling and working really hard in high temperature outside going up mountains and hills. I have two issues I want to improve:
1)Poor airflow on this 2007 ford Chassis design. :E The front air intake panel/grill is restrictive, poor design - hence the new Ford grills that came out in 2008 with ALL their truck models - HUGE 'breathable" intake grills. After looking a mulitple options over several years with many shops unanimously agreeing the engine compartment is TOO tight for any inside additions/modifications. Hence the need to increase airflow in the engine. I have a friend who will make two custom air scoops for my hood to force air in the engine and over the top of the back doghouse area. They will be customed made and painted to match Ford hood. It is a VERY different idea and will probably look cool too! :)
2) HEAT coming up from underneath...under the floor panel.:M I have Dynamat installed but I am considering doubling the layers. Yesterday a muffler shop told me they have seen a few rigs come in with some type of sprayed-on insulation UNDER the cab area...adhered to the metal floor ON THE OUTSIDE under the cab area. They had NO idea what type of companies do this. This makes GREAT sense if I can figure out who and where I can have this done. The shop told me it makes sense to try and stop the heat BEFORE it passes through the metal cab.
Therefore, the inquiries to see if anyone out there has experience with spray insualtion UNDER the cab area...and if so, does anyone know what type of business does this work? Is it even feasable? I have spoken to so many RV shops, Muffler shops, etc and ALL of them have told me to NEVER EVER wrap your exhaust pipes,header areas with wraps, muffler wraps,muffler 'blankets' or otherwise even though these products exhist.(wrapping on race cars, etc, they say is a different situation. I have been told several times wrapping will hold the heat in the pipes and over time over stress the metal and cause cracking, exhaust leaks and other horrible costly damage. The exhaust system needs a place to release it's heat naturally. So, wrapping the exhaust anywhere is out of the question. I have been told I just need better air circulation and better heat barriers. I already have the heat shields underneath, but of course, the shields are only a certain size where heat easily moves around the edges and up elsewhere.
