Then again, I could just throw in some VRLA wet cells 8Ds and call it good. ("throw" may not be the right term however).
Seems to me about the "easiest" solution would be AGM 8Ds, assuming you have somebody else hump the weight.
Use the same box(es) you've already got with no modifications, no new interconnects, no worries about off-gassing, no subsequent maintenance tail and no watering system required (contributing mightily to that "easiest" adjective).
Assumes capacity will be sufficient, and assumes your wallet will stand the gaff.
From what you've said about not having time to be away from the dock as much as you'd like, seems like capacity could be fine.
And you wouldn't necessarily have to buy premium AGMs. If, sometime down the pike, you decide capacity isn't sufficient, you could replace worn-out non-premium AGMs with a better engineered system that might meet your needs better going forward from there....
Just thinking out loud on your behalf...
