did they say how long it takes to send it in and get it back? now you have automatic leveling, so I will add something I would have stated in my first post.
If switching to lithium when you have an automatic leveling system, find out what the max amperage that the leveling system can pull is and buy enough batteries to be able to handle that, let me explain.
So let say for example your jacks are max 50 amps each and can run all 4 at the same time (mine will only run in pairs, fronts, rears or sides). that would be a max draw of 200 amps. so when buying your LiFePO4 batteries you have to see what the manual continuous amperage is and buy it so your not running at the top of that max. so most 100 amp batteries have a 100 amp continuous output. so for 200 amp possibility I would buy three 100 amp batteries. now if the batteries have 150 amp BMS like I used to build mine I would buy 2. you may never need to use that full capacity but for that one time when you need it and don't want to trip the BMS protection because one of your jacks is acting up, its gold.
