Are lithium batteries worth the cost?

When going camping, I am taking batteries from my sedans and boat.
No cost to me.
AGM batteries were design for upside down applications and are excelent for what they are design.
For camper use- it is just led-acid battery.

In defense of AGM, I switched to AGM in the belief that as they got older, there would be no crud build up between cells that could vibrate lose while driving along rough forest and backroads causing cells to short out. That has happened to me twice with the truck battery and twice with the TC batteries while using FLA batteries. I now have AGM all around, matching electrical characteristics, and never had another cell short out from vibration like driving lots of washboard gravel road. Just my 2 cents.
