Crown batteries are EXCELLENT batteries. Since you don't need to be concerned about tongue weight & you got a great price on them; why not??? The only real negative I see is lifting them out of the truck and onto their resting place.

Look like some pretty sweet batteries for the homestead!
The biggest thing I like about lithium for me, other than weight, is having no concern about fully charging them every so often. I often go for many weeks when camped under trees and clouds in the Pacific Northwest and rarely get back to full charge. It saves a lot of extra generator runtime. It is especially helpful when camped in provincial and state parks with limited generator hours or in the desert during the mid-winter months.
