Lifepo4 battery in 1990 Lance?
Will putting a 100ah Lifepo4 battery in a 1990 Lance with a single battery compartment work right?(picture below of converter/charger)It would basically double my house capacity from my currant Gro...

You need a charger that will do 14.4ish volts--that one only does 13.6 volts. (you can swap that out for , eg, a PowerMax to solve that) You need a Trimetric monitor or similar to keep track of your AH and SOC, because the voltage per SOC does not change enough to be able to tell your SOC from the voltage like you can now.
Idaho gets cold at times. You will need to solve the cold weather issue with those Li batts. (Some have tried this with heating pads etc.--don't know how well they are managing--you need power to the heat pad, eg)
You would get more usable AH, but not twice as many. The operating range is more like 80% of the SOC vs 50-60% you have now.
I was able to carry more AH worth of batts for the TC by putting batts in the truck bed in front of the wheel wells and run wires to inside. I connected/disconnected those batts when sliding in/out the camper with the camper part way in so I could get at the wires , and when they could reach. (That door some TCs have at the bottom left side that opens into the truck bed comes in handy too)
Another approach is to choose SiO2 for the TC where you get the extra AH same as Li, but no worries about cold temps. That is what our TC has now, but not for the reason to get extra AH. Our reason was to get the high discharge rate they can take (for the inverter to run the MW).
Li can do that too but they cost so much more --although that might be changing since the prices of both Li and perhaps SiO2 are apparently changing in some markets (not "up here" yet AFAIK)
