Just got some info about tank treatment..Happy Camper Tank treatment(you must buy online) is the best treatment for tank smell and keeping it clean.....Guy said rid-x is probably not going to work takes too long and does not have enough enzymes to get a bad clog...
So I ordered some from ebay and we will see..I will do the back flush thing too....fingers crossed till I try to dump again that I do NOT have to get into that nasty stuff again...Thanks again for the great responses and info....This forum has save me plenty of money and time over the past 5 years(been full timing that long).
Thanks again,Tom P.
