Batteries life while drydocking

[encantotom]

hi all,

i spend most of my time fiddling with my newell in my driveway rather than using it....my time will come. while i was out of town the breaker popped for the coach and there was no AC hooked up. my wife ran all the interior lights while working inside and the fantastic fan for most of a day. after a day of that and another 3 days of sitting batteries were almost dead.

so my quetions is this,

how long about can the coach sit and still have battery power? (i know a loaded question depending, but any times and boundary conditions you guys have from practical experience?

do any of you have a switch to isolate the batteries from discharging when not in use? my coach does not.

by the way, i only have a total of 4 8d batteries.

i am going to take a long trip this summer and while on a cruise will need to have the coach parked for 8-9 days. i dont want it to be dead when i get back. i guess then i just leave the merge switch in not merged mode?

also, i guess i need to see if the merge solenoid is actually working....

thanks

tom
