Dretynfn has a dual setup, but not sure which one.
If you don't have air, then there is plenty of room to mount a battery (or two)
in the air compressor area. Run power to the charging circuit and you'd have a good power soure at the rear of the vehicle. </div></BLOCKQUOTE>
You'll have to make sure the battery is completely protected from the elements. I've seen even Optimas vent after they've gotten wet. I had one do that after washing the engine bay on another vehicle. </div></BLOCKQUOTE>I'll have to disagree. You can dunk an optima and keep going. Even regular batteries work fine when left to the elements. We have old pieces of equipment with exposed battery boxes that just sit out in the weather all of the time.
As far as the optimas are concerned, they are sealed. If it vents, then there is a breach in one of the cells. The other thing with optimas is that you can mount them sideways, diagonally, just about anyway you need and they are fine, since they are sealed.
