So my problem is the RV is plugged to power all the time. I keep it at my home and keep it to shore power to maintain the Frig, run my small dehumifiers etc. Also alternately run AC's as in the summer in the South it gets pretty hot and it just maintains all the systems. The chassis battery was
replaced March 2019, the house batteries are probably late 2017 or 2018 ? they all came from Walmart so who knows. When I isolate the issue I will share. Right now I am checking the battery first.
