I thought about it, but what I�m going to do is make sure everything is sealed. Make sure there aren�t any sources of water ingress from the outside, get handy with a caulking gun. Finish up with sheet poly before the finish panel. Course I won�t be able to do the front doors. But the other night while on the highway I noticed that the wheel hump beside the seat was absolutely freezing. I�m sure if I spat on it it would have frozen. You can have all the heat you want blowing but when that kind of cold metal lines the van �wow. I�ll have to think what I should put down around there. Maybe carpet underlay or something, underneath the rubber mat. On top of the paint/cellulose. There is also a huge amount of noise coming from the nose and and floor area.
