my 15 f250 is due. it doesn't get run much, less than 5k/yr.
or does it not really matter? walmart, etc? thats kind of been what i have done in the past.
I have a 99 dodge diesel that gets run very little any more. It's not parked in a place where I can get electricity to it to run a battery tender so I had a solar tender on it but that only lasted a couple of years before it crapped out. I got some battery disconnect terminals and simply turn them to disconnect the batteries when it's going to sit for a while, that's done a lot better at keeping the batteries from discharging.
