How many total amps will you have with your new battery bank and what type of converter will you be using to charge them?
Not sure on the total amps but I believe my batteries are similar to this model from
Trojan Battery (link).
I have a Samlex charger but since I rarely setup camp near a plug I'll mainly use solar panels and the van's own charging system.
I noticed that the battery bank will be directly behind your seat. Will there be enough weight on the right side of the vehicle to off-set this?
The "kitchen" and all drinking and waste water will be on the opposite side so I'm hoping that balances it out.
Will you be installing a Trimetric battery monitor (or similar) to keep track of your battery usage?
I have a couple simple digital displays for battery volts and amps. Will be using that to keep an eye on things but nothing I'd call a true monitor.
