I want to switch my Fleet camper to (2) 6 volt batteries in order to get more amp hours. However, as you can see in pics #1 & 2, the adjacent compartment extends above my 12 volt battery 1". The 6 volt batteries won't fit with enough clearance. I removed the vent grill to see what's in the adjacent compartment. It appears to be some controller with an exhaust fan on the left side (pic #3). Since the batteries are and will be sealed, I don't see why I need the separation between the 2 compartments. However, their's an angle brace supporting the upper cabinet that is attached to board that extends into the battery compartment (see pic #4). Any suggestions as to how I can safely modify the cabinets to accommodate the 6 volt batteries? The pics can be seen at https://www.facebook...97997920276293/

That looks like your Iota battery charger.  I suspect you can modify the cabinet as you wish, but it might be easier/better to go LiFePo.

LifeP04s won't fit. They're even bigger. FWC wanted $700 to modify the cabinets and install (2) 6volt batteries, as they suggested.

Have you determined taking showers is the highest battery demand ?

 

When we traveled extensively in a camper van we found lots of local options for finding showers.

 

Just a thought,

I live out of my FWC near a job site that has no showers Which is why I got the indoor shower.

Not only are LifePO4 12V batteries  larger, but a 100Amp one costs around $1000...

 

A pair of Fullriver 6-224 batteries will cost around $600; more if you have them shipped.  I know you're unhappy with 4WC, but another $100 to modify the compartment and install the batteries doesn't seem excessive, since it's probably a 1-2 hour job.  You can offset some of that cost by selling your existing 12V batteries.

 

In my opinion, before you invest $600 or more in batteries, you really should determine your daily amp usage.  It doesn't cost anything to do so, and it's fairly easy to do.  A simple spreadsheet is all you need, and there are many solar threads available.  Once you determine your daily usage, you may find that changing your usage patterns may be needed.  For example, you may find that turning your furnace thermostat down, reducing/eliminating shower time, reducing lighting usage, or other measures may help.

I've modified my usage patterns & haven't really gained much in amp hours. It's only during a rainy week that my solar system is inadequate.
