We are considering buying a mid-level diesel pusher. One consideration is how well insulated are the walls/floors/ceiling. It doesn't appear as though the manufacturers publish the R value information for their coaches. Does anyone have any specific recommendations by brand on who has good (or bad) level of insulation in their motorhomes?

Newmar is one of the few that will advertise the R factor. Yes it does make a difference as to the rating and your comfort or liveability in the MH.
Also check to see if there is ANY insulation in the storage compartments. This will seperate the men from the boys.

Dig into the specifications on the various makes and models you are intrested in. You may also want to look at Tiffin & Winnebago.

Winnebago doesn't publish theirs. There have been many posts about Winnebago's low insulation R-values. Winnebago builds units that are good for moderate climates at best.

I agree with a post above that Newmar builds good solid insulation into their units and is willing to provide R-values.

Far more important than R value is air leakage. Many units do not have any insulation on the front cap. Some are not sealed well between the basement and the home. Even clearance lights have been known to be a source of air leaks. I remember reading about people with Alfa's having ac problems and the solution was to have the unit leak tested and fixed. Made a difference.

Newmar is the only mfg. I know of that builds the coach 16" on center with both block foam insulation AND fiberglass spun. They also insulate the studs from the interior wall. To the best of my limited knowledge, all other mfg.'s lamanate the walls with block foam insulation between studs, but no insulation from the stud to the inner wall.

You can view the Newmar contruction at www.newmarcorp.com
