I am in the middle of converting a 4x4 van in a class B camper and am coming up on the time to run freshwater. My only question is do the water lines or tank sweat? My concern is obviously if they do the water is going to do damage over time, thanks for any info!
I think you can make any tank sweat if the contents are lower than the dewpoint temperature and the walls are uninsulated. My room temperature 7 gallon containers do not sweat appreciably. It might happen with 50 degree well water added on a hot, humid day.
Note that foam coolers tend not to sweat due to lack of heat transfer.

i had a pan made that goes under my water tank and pump i added a drain to the outside, any leaks and it drains out side.theres a sheet medal shop that makes duct work here they made me one cheap,i soldered the corners and made it water tight,drilled a hole to the outside thru the floor and put in a copper pipe and soldered it in place its just big enought for the drain from the tank and any water leaks or spills i may have.the reason i did it was i had a small leak i didnt know i had because of carpet covering the floor under the tank when i did find it i had to tear everthing out and repair it,had some rot in the plywood floor under the tank,it will never do it again in that spot and do damage.

I will be traveling through central and south america and im sure there will be plenty of hi humidity hi temp days so im pretty sure sweating tanks is an issue, which also means i may need to wrap the lines with something? Glad i thought of this thoug, i like your idea of the pan, how much did you pay for that? I may just go with a cheap tarp or something, maybe even some heavy plastic, but draining it through the floor with the tank drain sounds like a good plan. Thanks for the input!
Tress - My first motorhome was a 1971 Dodge Champion with an unusual water system. It had a steel pressure tank which had a rubber sealed gravity feed connection (much like a bung on a 55 gallon barrel) and a garden hose connection with check valve. Instead of a water pump, it had a 12 Volt air compressor which would pressurize the tank. It also had a "schrader" valve (looks like a valve stem on a tire) for pressurizing the tank at a service station. This arrangement worked so slick that I had to share it with someone building their own water system. It was as quiet as a home system and the air compressor served double duty airing up tires.

I have heard of this idea thrown around, sounds great and if only i had known about it before i started teh project i would have certainly considered it, especially since my air compressor is already right there! Either way its too late now but i like the idea and ill keep it in mind for future projects, take care and enjoy the time, thanks.
