How to remove/kill mold behind RV walls?

I have a 1982 Dodge Xplorer 228 campervan, and recently I noticed some mold growing on the walls of the van.. probably because there is a leak in one of the back bedroom windows.. so I cleaned everything I could with white vinegar. I then tested the air for mold spores and it tested positive. So obviously there is mold behind the walls. Problem is I have no idea how to get at it. I would literally have to tear out everything.. the cabinets, the closet, the sink, the plastic walls themselves if that's even possible. There has to be a better way right? HELP!

  • Be careful with ozone. It is highly corrosive to metal, and may make certain plastics become brittle if too much is used.

    A 36 year old vehicle? ... there's your answer if you really think it's worth salvaging, especially considering the serious health risks exposing yourself to mold spores.
  • I had a major roof leak on our Southwind. I ran a dehumidifier and an ozone generator.
    I didn't tear anything apart except for a little ceiling trim at the wall.
    Everything dried out. My moisture meter is reading zero on the walls, floor and ceiling.
    I have no smell or soft spots. Did I get it all? I don't know. I'm satisfied with the results. I will run a dehumidifier in the RV this summer, just in case.
    Do you have any trim you could remove and drill a few small holes to help with air circulation.
    I think it's worth trying before you tear the wall apart.
    Let us know how you make out with your problem.

    Get your leak fixed ASAP.
  • Would an Ozone Generator take care of it? I've heard that mold foggers don't actually work and are a scam. Is this true? Apparently they don't actually kill or remove anything and the fog just attaches to the spores (like moisture always does) and the spores then settle to the ground effectively removing the spores from the air so that when a test is done- none of the spores land in the petri dish and therefore it appears that the mold problem is gone. Can anyone actually verify this? Is there anything else that can be done?
