Are lithium batteries worth the cost?
I can carry two group 29s in my AF1150. Are they worth it?

I just finished converting to lithium. Two 100 AH battle borns moved to the basement storage in our Bigfoot. I also put a 40 amp Renogy DC to DC charger to charge off the truck. Monitoring is with a Victron 702. Also a Progressive Dynamics 55 amp lower power center conversion to a lithium compatible charger. All new 4 GA cables

I can't wait to hit the trail. I don't wonder if it will be worth it. I already know it totally is.
We did a very similar upgrade on our Northern Lite. Installed a single, group 24 size 200ah DIY LifePo4 cell pack and a Renogy 40a dc to dc charger.
Used 2 gauge cable for our Renogy install. Surprisingly, it allows 40a of charge current with only a 43a load on the alternator. Also installed a battery isolator to isolate the Renogy (and the truck’s battery) when the alternator is off-line.
Elected to keep our standard 3-stage (13.2/13.6/14.4) 45a Progressive Dynamic converter (and Charge Wizard) to charge our LifePo4 cells vs. using the single stage (14.6v) 45a PD lithium converter. We prefer the option to float the LifePo4’s at 13.6v with the Charge Wizard.
Like you, we’re thoroughly pleased with our upgrade. Well worth the time and money for the added stability and performance.
