Been using a blue top for about six years now. I disconnect it during stretches camping where the doors are open a lot but the truck isn't on. A while back it discharged over a two or three week period of disuse. Since then, if it sits, I unplug it. Also since then, if the headlights are left on more than about 30 minutes without the truck running, the battery barely turns the starter.
Since then it seems to have recharged ok, but I'm still paranoid about it.
I'm going to give Odysseys a try when I go dual remote, but not for any particular reason than to try something different, I think. On paper, the Optima is more power for the size and weight.
