Batteries not holding charge ???
I have 2 year old deep cycle Interstate batteries, usually they hold a charge for about 2 months but recently its much shorter than before. Is there a way to check the RV charging system? When I plug ...

I've got the same batteries that are 2.5 seasons old and they read 13.5-13.8 when plugged in. I put solar on the roof during the 1st couple months that we bought the trailer so the batteries have always been charging except when the sun goes down. In the winter the trailers plugged in 24/7.
It almost sounds like they need to be bulk charged and the RV's charger's not getting them up to bulk so they can go into absorption mode then into float.
When on solar my batteries float right around 13.8 with nothing on them except the normal parasitic draws.
When all charging is off they sit at 12.7-12.9 or so.
If they've dropped below 50% too many times then you just may have damaged goods.
