Good By Excess Dog House Heat

I can't wrap my brain around going to all the effort and expense of installing heat insulating material instead of merely setting the cab air conditioner controls differently .... or at least trying this approach first.

However, maybe our cab flooring/doghouse heat issue was not as severe to begin with. Our Class C's V10 E450 has metal heat shields installed between the two under-cab-floor exhaust pipe runs and the underside of the cab flooring. These shields have a healthy air space between the floors and shield and between the exhaust pipes and the shield for a good air space insulating affect. I think that Winnebago installed these, but not sure. A Ford dealer said they thought that the shields were not a Ford installed item.

Perhaps this is a construction feature to look for before buying a Class C built on the Ford E350 or E450.

It's now clear why Ford does not install the higher horsepower 3-valve V10 in their E350/E450 vans ... even more heat to get rid of in a confined engine space.

Your suggestion about running the ac on the mix setting sounds interesting. My wife has complained about heat around the passenger seat from the floor, on our previous E350 and our current E450. I have never felt floor heat on the driver's side on either vehicle. The only problem with your suggestion, in my case, is that I normally travel with the dash ac off, and the generator and roof air running. :B

I always thought the main reason they don't put the 3 valve engines in the E series vans was because they wouldn't physically fit. :h
