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...

By the way...we DO have those same heat shields around our pipes. EXACT same shields. They just dont' do the job and shield enough area.
Hmmm ....
Our Itasca floor has fairly heavy carpeting and heavy padding under it as delivered by Winnebago. Our floor does of course get warm during hot weather driving, but nothing overly disagreeable about it. The MIX A/C pretty much takes care of what heat there is just fine. However when set to MIX, one must have the temperature control all the way into the blue (cold) position and use a fan speed of 3 or 4 for it to be effective. A fan speed setting of only 1 or 2 will not be strong enough to counteract heat coming up through the carpeting. And as I said, I have never seen a need to stop using as much A/C as we want regardless of how hard we thought the engine might be working relative to outside ambient temperatures and road grades. I assume the temp gauge will move if we're ever operating outside safe engine or transmission heat limits and so far it hasn't come anywhere near indicating showing too hot of a condition ... including pulling up long grades outside Death Valley.
However our E450 is carrying around only an 11,800 lb. Class C and we rarely tow anything except a small aluminum boat, so maybe that helps a bit to keep heat buildup lower in the cab floor area.
