2006 Monarch PDD30
Hi - I'm also trying to find any specs, drawings or locators for my Black and Gray Tanks. My sensors went out about 2 years ago, although all other sensors in the panel work fine, my local tech replaced the Circuit board, twice, to no avail. He as well as another tech said it would cost many many man hours to track down the problem. They both said they couldn't locate the tanks to even start. REV RV said they didn't have any documentation anymore.
Any help is majorly appreciated.
