Chassis battery disconnect
I have a 2011 Jayco Greyhawk. Would it cause any damage to any electronics in the rig if I disconnected the the chassis battery when it is stored??

My electronic battery disconnect stopped working so I installed a knife blade switch on my battery bank. Stopped the discharging, but may have an unwanted side effect. Just completed a 900 mile trip and my mileage is almost 1 mpg less than I got on last summer's trip. May be coincidence; will require more tracking. I did have a roof coating installed but can't conceive how that would create enough additional drag to make such a difference.
1 mpg difference on a trip you made last year compared to same trip a year later may have nothing to do with engine electronics, which usually normalize from the reset within the first couple of hours of driving. I regularly see 2-3 mpg difference trip to trip, and segment to segment on a long trip, from changing driving conditions, more importantly wind speed and direction. My 8.3 mpg can drop to 6.5 into a headwind and rise to 10 or 11 with a good tailwind.
Similarly, my full size van will range from 11 mpg to 16 mpg with wind and cruising speed as factors, and will even get up to 18 mpg in the winter when not using A/C is combined with a tailwind.
