i am currently having my system installed. It consists of an 18 FI BTL, SAZ 3000D, ZAPCO REF 1000.4, EA 250 amp alternator and a Powermaster D3100. I was going to have the D3100 installed in the back of my 06 Navigator but the guy told me he thinks it would be better to put it up front as a stand alone since i only have one AGM battery and the front battery is stock. Will (1) 3100 and 250amp alternator be enough to maintain for say a month or so until i can get another Powermaster battery?

I would think you would be fine as long as you watch your voltage. To me it makes more sense to leave the battery up front until you had the funds to replace that one. That way you could've had the D3100 in back and you would at least have battery bank that consists of 2 batteries and not just 1. But I've laso heard not to mix AGM with regular gell cell or lead acid batteries, but I know people who do it and have not had any problems.

yeah that's what i thought but some people swear by not doing it but i've known guys to do it also and caused no problems that i could see.
