Drew,

Yes, the batteries travel in the back of the SUV but they are in battery
boxes which are tied down. I'd still feel better using the non-wet batteries
though. I also might consider one bigger Optima vs. two smaller other
batteries to conserve room. One thing to help is to manage power better. Due
to interstation interference issues, we run a 2M amp while mobile but only
run 50W direct from the 100D when stopped. So on Sunday morning, my rover
partner had the 100D at about 7W out to drive the amp but the amp was off.
He was ripping the Qs with no trouble at all. Granted we had a great
location, a new 2M7 and good feedline. There are many times when we could
turn power down a touch, or a lot.

The Interstate 6V batteries look line a good option in wet cell.

I have till about mid January to figure this out!
