I would like to add 2 more house batteries to my GT 373. The current 2 batteries are under the stairs in a tray and I can't see anywhere to add some more that I can still access them to add water, etc.
I thought about building some sort of outside air vented box to put in one of the storage compartments but I was a bit worried about the weight capacity of the rotocast plastic used for the bins.
I am using Trojan T105 6 volt batteries so they need to be outside or at least vented.
Has anyone, especially a 373 owner, added more batteries and if so where?
Also, does anyone know of a weight limit for the bins.
