We are new to motorhoming and need to hear from the experts! We have had a pull behind for years. So my question....When we dump the smell is horrible inside the coach. I dont know if we are doin...
Do you think the odor is from, sorry, you or leftovers from previous occupants? Filling it up with just fresh water and then dumping might help you figure out whether the odor is from new "stuff" or old stuff.
When we got our gently-used new-to-us motorhome I bought a couple pints of bleach and one of those Camco Holding Tank Spray Wands at Walmart. I sprayed the black tank, filled it, then added the bleach and waited.
You might try that, if the RidX doesn't clean up what ever is down there.
