AGM batteries were a godsend for me. In my case, the AGMs made my system possible.
I have living space issues because there is not enough outside space for the AHs I need.
There are no batteries on the tongue. I use that space for other cargo.
The AGMs are inside the van and under the bed/dinette in the TT. Some have suggested that they could have been wets if I bought a sealed container and then drilled holes for vents in the van and TT. That only makes maintenance more difficult and dangerous. Nogo for me as I put the AGMs in somewhat inaccessible locations where an acid spill could occur during water maintenance. There goes any cost savings.
I also believe I need fewer AHs than wets would have required. That saves space and $.
