Sorry about delay, here's writeup on my battery/charger setup: http://www.iral.com/~albertr/EVC/battery/battery.html
Let me know if there're any questions.

Albert,
This is amazing stuff. I want to build something very much like this. What were the specific reasons you chose the Magnum instead of the Promariner Dual charger? Anything aside from the higher current? I like the dual (house and starting) battery charging aspect of the Promariner (aside from the price). If higher current was the main (only?) reason, then what have your charging times been after discharge? Enough of a difference to justify the price difference?
Also, looks like you lost quite a bit of storage space in the rear battery compartment? I use that room to carry chocks, grey water drain, jump start cables, some tools, hammer, cordless drill, etc. Did you find the reduction in storage room noticeable? Were you able to use the now empty magnetek area to stash some stuff?
