On the bluebird I got, the water is designed to run along the skin and into the wall channel between the chair rail and outer skin, theoretically keeping the moisture outside of the cabin.
I had tons of condensation before I added insulation. Once all the insulation was in place, I did not have any condensation issues.
The only time it gets humid is if the heat is off, everyone is in the bus (family of 6) no ventilation or heating is running and its cold outside (in the high 30s farahenheit or less)
Add some heat or air movement and its a non issue again.
So, insulate!

My thought is, every morning I notice a RIDICULOUS amount of condensation on my floor and ceilings (everything is gutted). While this likely has a LOT to do with the fact that there is no insulation, I still wonder what the longterm effect of that condensation will be on furring strips laid on the floor even if they are fastened to the sides of the bus instead of through the belly of the bus (which I'm not doing).
"Ice and Water" SEEMS like it would make a lot of sense in terms of sealing out "anything" that would try to sneak up through the metal floor through condensation, but am I missing something?
Working on a big metal can has really opened my eyes to what can happen over time with things like water and moisture and i'mw ant to seal against it as well as possible.
I know i know... i'm not going to have this conversion for 50+ years, but i'd sure like it to last like I am.
