I went from an 83lb 150 a/h lead acid battery to a 33lb 125 a/h lithium in large part because of the weight. My battery lives on the tongue wrapped in a battery heater wrap that is powered by the battery itself, so I can charge in below freezing temps. There are now many batts with internal heaters that would be an easy solution to low temp charging.
Besides the weight savings, the other main reason for us going to lithium was the faster generator charging to full on low solar days. I've cut my genny running time by 2/3 when parked in the shade, which is typical for us on days we aren't traveling. I do have a good stand-alone 60 amp charger with a lithium setting.
You can use almost all the available a/h in a lithium. If you don't have a good battery monitor and are just guesstimating the amps in and out you'll have to be conservative and leave a decent buffer on the bottom end to ensure the fridge and furnace keep running through the night.
