I've got a DEKA in my rover. I've done everything I can to try and murder it. No dice. After 4 years of failed alternators and starters and general debauchery, its still good. Also I see it is what most of my customers use in their machines as well, which is cool.

Excellent product, I'd go with that.

Beyond, it will determine your usage. Obviously going LED will save a bunch of power as will being mindful. However for a long weekend of non-caring about power usage, you'll probably kill it off. Which is fine because who cares if the battery is dead at the end. Also you can setup the wiring such that your tow vehicle can trickle charge the battery when being towed. A couple hours at 5~10 amps would help a lot.
