Good to hear. I did the Progressive Dynamics PD4645V converter replacement, and installed two more in friends Casita's here locally. The 4 stage charging system is much better than what Casita provided, theirs had a much steady higher voltage and boiled out your battery. Easy to do and you will like it.
Pick your projects some day you can remove the roof air. It puts weight up high and noticed it would flex the roof and suck in more dust.
Thanks for the follow up, Patrick
