We have a 2020 24F. One of my first projects was to replace the totally inadequate dealer supplied house battery - which was probably mistreated worse than a red-headed step child.
I modified the battery compartment by slightly raising the step to accommodate two GC2 6volt lead-acid batteries. Then I upgraded the factory solar charge controller to a 40amp MPPT. Finally, I installed two 100watt panels on the roof.
No worries now about "parasitic draws", and boondocking, the fridge (propane) and furnace will both run all night without a hitch.
Without a doubt - the single biggest improvement Thor could make is a minimum of 100watts of rooftop solar on EVERY coach it builds. It completely eliminates the "dealer destruction" of batteries... especially if it's a sealed battery.
