Hey Jerry

Sounds good one project at a time with these units.

I did find a guy that works on Prevost and class A coaches that lives near me.

Probably going replace both inverters because they are not working at all then maybe see if three or four

house batteries would be sufficient.

Hey Jerry

Did you end up changing out your batteries and what did you go with ??

I have the exactly the same set up as yours mine is 1993 Marathon XL

Also have you upgraded the inverters ??
