Yea, I'm going to want to see long term data sheets on this one. The Volta packs are Lithium Nickel Manganese Cobalt Oxide (NMC) so I'm not sure what they are doing differently to get an additional...

Maybe, but winnebago made a test revel last year with lithium but canned it in favor of 300ah of AGMs. Maybe I'm wrong, but I still think Winnebago is going to play it safe for a while longer....

Lithium can be charged below freezing, but you are not going to get max life out of them. AGMs can be discharged past 50% but you are not going to get the max life out of them. Best practice...
