4 batteries in a 29M?

[VetPartTimer]

Anyone been successful fitting 4 batteries in the battery bay for a 29M? Or perhaps making some sort of a modification to do so?

I dry camp mostly and run 2 6V CG2 batteries, but would like a bit more/longer power. In my previous toy hauler I ran 4 6V and it was pretty much perfect.

It doesn't look to me like there is any way to get 4 the current battery bay, thought I'd see if anyone has done this and how.

Thanks!

I have 3 12 volt batteries in my 2019 29m. I see the only way to make room for one more battery is to extend the shelf where the batteries sit.

I also do a lot of dry camping, and I have three kids who always have their laptops plugged into the inverter outlets. I installed a third 12v deep cycle battery in my motorhome last week. It was a tight fit, but it worked. I don't see how you could add a fourth battery. You mentioned that you are using 6v batteries. Perhaps if they are smaller than the 12v batteries you could fit four, but you would have to measure your batteries and the space to see if you could make them fit, especially since they have to be installed in pairs to get 12v.
