Electrical system

Monaco Dynasty Owners! Do you find it necessary to turn off the chassis battery cut off switch, the house battery cut off switch and the engine bay start switch when not plugged in or on generator power. If I don't do this, within 4-5 days, my batteries go down to the point of not being able to start the coach and interior lights very dim. Looking to hear others experiences.

I don't own a Monaco but they put in disconnect switches for a reason. There are parasitic loads that will drain the batteries when sitting and no shore power. 4-5 days seems like a pretty short time frame if the batteries are good but I don't know what type of loads your Monaco is placing on the batteries.

I don't have the problem, my coach came with an 85 watt solar panel and controller and PO installed 2 more 125 watt panels. This keeps my batteries up and allows extended boondocking if we monitor power consumption.

But I do know that there is parasitic draw so using the batteries disconnects is the only way to prevent battery drain.

I have found that most of the so called cutoff switches installed in rvs merely reduce electrical draw and not completely eliminate it. We installed (2) heavy duty Perko switches, one for the start batteries and one for the house batteries, which do what oem switches "should" do which is basically kill all chances of parasitic drain by anonymous devices. We had them mounted inside the battery compartment next to each respective battery bank.

Are these Perko switches easy to install? How expensive? The dealer installed two brand new batteries at time of purchase nine months ago. I've since installed two 1260 CCA batteries from Freightliner. Coach kept in shade most times so oem solar panel not helpful. Will follow-up on suggestions and thank you all!

My manual says that I can park myMH for 72 hrs without shore power and batteries disconnected. Things like CO detector, propane detector, steps are still powered.
