Just got delivery of my 2022 385FL. Furnace flow to front living is great. Furnace air flow to rear half (half bath, master, rear bath) is virtually non-existent. Is there a separate fan to distribute to the rear?

Congratulations and welcome to the forum.
I am unaware of a separate fan.
In most cases, reduced air flow is a result of disconnected, torn or collapsed duct work.

Cottonwood,
We too, have a 385FL. It is a 2024 and recently I was investigating a gray tank venting issue and to access the area, I extended the tray and climbed thru the forward side storage area. I was able to unscrew the wal panels and remove to access the void behind. There you will find all the duct work to the rear of the coach(ythe 1/2 bath, the bedroom and the duct headed to the bath. There is also one that heats the storage area. I have attached pictures of that area. There is some opportunities to clean up/shorten the ducting. You may also want to look at the area behind the nautilus wall to ensure all ducts are fastened to the heater. We have a little lower flow back in the rear bath and bedroom as these are the furthest locations from the heater. If you find kinked or crushed ducting and make necessary adjustments and flow is still too low, something like what Jim has shown may work as I used them in a residential application years ago with good success. But first mmake sure everything is conected and not kinked or crushed.
Good luck, Congratulations and Welcome to the forum. We love our 385FL,
