Towing my 701 back to the repair shop,  the towing driver ask me to opon the front slide tray in the front tray, I don’t know how to as I never did it, and the engine could not be started as the battery seems too weak. The both batteries in 5he engine compartment shows date code: 3/22, so I believe they are still relatively new. But after this coach being worked and waiting for parts for nearly 3 months, either the batteries have exhausted or it has big drain somewhere while in engine off mode.
Are there any battery disconnect switch somewhere so I can totally disconnect it to prevent battery drain?

UPDATE:

The towing driver wasn’t able to tow it because the rear height being too low.
