Thank you all for the feedback. We are very much lacking in knowledge here and trying to learn as much as we can before taking it in for service so we gain the knowledge to troubleshoot ourselves. Did not get a chance last night to test the voltage or try flipping the disconnect a few times, but will try that tonight and report back. We are totally shooting in the dark because we are so new to this and not exactly sure what should be doing what as far as charging, keeping charged, ect.
One thing I will mention is when we went to replace the house batteries, there was a trickle charger on the chassis battery, plugged into the outlet in the entry and the person said that was unusual and it should instead be attached to the house batteries so we moved that.
If anyone has any good resources for reading up on basic RV electric, please send them my way. I have done a great deal of googling but it seems that there are many variations of how things work in different RV's that I am not sure I am gaining the correct information for what pertains to ours.
Thank you all again.
