OP here,
Thank you all for your responses. I now know that I need to address the parasitic load that is draining my battery before I do anything else. I just was not looking in the right direction.
I pick up my RV this Friday from the underground storage site. It has been there since the end of October. We did go up and check on it but it isn't the same.
I called my dealer and he informed me that the disconnect DOES NOT kill all power. There is definetly power to the one slide that blocks access to the rear of the RV when closed. He claimed that this was intentional as a safety feature. He also suggested a few other things such as the gas monitor.
Trying to find a way to change the wiring to the slide and whatever else might be drawing current I have decided that since I have a brand new in box Blue Sea Battery disconnect that I purchased to install on my old 5th wheel that I will install this switch directly off the battery cable.
Battery DisconnectThis will eliminate a draw from the battery while stored. I will charge my Deka battery and have it tested at a parts store to make sure there is not a dead cell or anything else wrong with it. If there is then I will purchase a new battery at that time. If it tests ok I will keep it and save the money.
Thanks again for your help!
Dave
