Anti mold and fungas spray

Household vinegar is a disinfectant, mild acetic acid and does a wonderful job of removing and preventing mold.

I'd wonder what was in the dealer's anti fungicide and if I could do it myself if interested before plunking down my money. I'd also wonder if the average RV is as airtight as modern homes; I kinda doubt it.

If you live in "wetter" Washington it may not be a Scam.

I've seen more then one used rig that had obvious mold/mildew issue. But then I also walked away from those rigs.

The winter clime in "wetter" Washington is hard on un-heated, un-protected RVs

Well let's see: Would you like toxic mold? Would you like toxic fungus? What about bed bugs, fleas, body fluid deposits? I say buy new or get it detailed to no contamination. Not just the surfaces, but the entire RV. Just make sure they are using non toxic cleaning products.

First time I have ever heard of it. Scam if you ask me. :h

I've never run into this but it sure sounds like a Money Grab to me... I'd pass on it. Save the money and use it for some bleach 'IF' you ever run into any mold.
