Hey Jesus! I appreciate your humble approach. Your rating as a C isn't fair - I would have never thought to paint over the holes for rust. On my install, I will probably spray paint onto a sponge brush and dab it on that way. Although, nobody will ever see the bottom as you stated, so no big deal. Nice install.
I have a 2021 2205s, and want to do this upgrade, too. I have been wondering if there is enough space to put them behind the access panel in the pass-through. Was thinking they might work/fit way to one side under those boxes next to the bed - I know the inverter is there. Did you happen to look at that space as an option? I haven't looked and measured yet. I recall there isn't a lot of space there.
Do you know of any good videos that show you how to put the cord back In like the awning over the slide out? Mine on my flag staff has started to work it’s way out .
I have a flagstaff 22fbs which is mostly the same as yours. Are you able to obtain a full charge of your lithium batteries without changing the inverter charger? Thanks
