Good morning! We will be joining the Alliance rv owners soon. Just ordered a 2024 29RL the 1st of Feb and now waiting (not patiently) for it to arrive approx 1st of April I'm told. Quick question for you, I am looking at putting 2 100 AH Lithium batteries in our RV and most of the batteries I'm seeing are group 41 size. Looks like the battery box is for group 24. Can anyone tell me the actual dimensions of the factory batter box? Solar pkg comes with a 320 watt panel, a Renogy mppt40 Amp controller and no inverter. Thoughts on 2000 or 3000 watt inverter and batteries anyone? Thanks, Mike
