I have notice I have water under the floor on the back side. I think it went inside after cleaning the van and now I can listen the water moving while driving, do you know if is there any way for the water to come out?
I guess that piece of information would have been helpful. Lets make this into the longest back and forth thread! I didn't know they made an electric nv til now. I don't feel like researching it. How are the battery's cooled and where are they located? Could they be cooled by liquid and located where the fuel tank used to be???? If you are positive water got in from washing it then I'm sure you would see water inside your van too. There are a few posts about the plastic/rubber plugs in the roof leaking.
