I have been RVing for over 30 years first in a tent, then a pup, then a tt now a class A.. I do a lot of research and have been a member of some RV forums for over a decade.. There is not a whole lot I do not either know or can not find out (See I do a lot of research)
As to the original poster's question in any thread.. My attitude is the only stupid question is the one you fail to ask. Thus I will be polite to the O/P.
However I do admit some of the fertilizer I see posted in respond to a question can indeed set me off. And there are many who believe what are, after all, myths.
Like the guy who posts about a problem with his 12 volt system (Only half of it works).....
So the knee jerker posts "Check your GFCIs" .... Right.. Now I do admit, some companies put the converter on a GFCI protected line (Why I will never understand but that's another topic) But if that was done not only would half the 12 volt systems give up, but the other half would too.
