Its raining all day today and I am proud to say we have no water leaks inside or in the bays other than the normal water when you open the doors. While check I noticed a lot of cold air coming from the front of the coach not only windows but under the dash as you can see on this flir picture the darker the area is the coldest, this area is right above the six packs on the floor and front cap. Has anyone had a fix for this?

Behind the panels on the driver's side are several pass throughs that allow various shafts and wiring to get outside. On my coach they were not well insulated with only a foam backed cloth panel surrounding the gap. I used some flexible closed cell insulation to fill the gaps and keep it all in place. Made a pretty big difference overall. No more breeze coming in from there!

That was in the back of my mind Rick more than likely thats going to be my only choice. Also the floor of the slides are really cold but having taken my slide down to bare bones I don't see much you can do there as the mechanicals take up a lot of space.

Any room for mylar bubble insulation?

[Jack Houpe]

It's pretty tight back there and no foam on the front cap might just insulate the kick panels.

[Wanderman]

Sounds like a good idea. I'd recommend expanding foam, but it would be a mess if you ever needed to get in there.

That being said, you can wrap a thin plastic bag around things and fill the bag with foam to fill voids. And then cut lengthwise to remove.

I like the "jam lightweight closed cell foam sheet into the gaps" method even though its far less efficient!

Yes, while I had my steering column out I notice the cable pass through the floor with no insulation around the wires. I really noticed outside when I was under the coach in the summer and I could feel the cold air conditioned air coming down out of the hole. It’s on my hit list to fill it with some expanding foam.

Just a word of forethought, before you fill the cable pass through with foam or anything else, install a couple of conduit paths.

As a person who has had to run wires through those pass through that someone filled with silicone, I would have appreciated having an open path instead of worrying about damaging existing wire trying to break through.

I feel you on the cold air coming in!! Brrrr There are soooo many wires under that dash too no rhyme or reason for them to be in such chaos. I'm going to try the closed cell foam route

I would try stuffing a plastic Walmart bag in there without breaking it then filling it full of foam.
