I did much the same but only installed connectors (Delphi Weather Pack https://theelectricaldepot.com/weather-pack-delphi-connectors?zenid=afaad1bd8a5f7d715509337017d83253 ) and a switching box to toggle between the cranking and aux battery of my Traxide system.
The jpg's below show the switching box, the Weather Pack connector that can hang thru the grill and the CTEK US3300 maintainer. I usually connect up the batteries about twice a year. It takes a week of charging overnight for each battery to bring them back to where the maintainer just sits on float.
I do have a cigarette lighter connector type solar panel that I have used as a battery maintainer for my plane but do not use any longer as the plane is now hangared and is hooked to a power cart.
I could set the panel on the dash for when parked all day outside and plug it into the aux socket that is now connected full time to the battery independent of the ignition.

I think we discussed this at some point.
I just rely on Traxide's affirmation that both batteries will be fully charged regardless of which one is connected to a charger. I have my underhood charger connected to the cranking battery, but my volt meter tells me that both are, indeed, charged after the charger has kicked into float mode and I disconnect it.
As to the earlier post about a Group 31 battery, if one is willing to ditch the battery covers, I think there is a reasonable chance that would fit. Just judging from the random things I have left lying around the engine compartment when working a still managing to close the hood. As to whether the cable would fit; I would think some modification would be necessary there.
