We have a Winnebago Adventurer 38T with basement central air, we are able to shut the bed room off and only cool the front of the coach.
My question is since the air intake is in the bed room am I helping cool the coach this way are since the air is hotter in the bedroom am I hurting the cooling of the coach?
Thanks for any and all comments!

if the only air return to the system is in the bedroom, when you close that room off it seems to me that it would greatly affect the air changes and air flow patterns. is there a measurable opening above/below the door that would be sized roughly the same area as the return?

When we had our Adventurer. Always left BR door open. Kept the whole coach cool just fine. There should be an air filter in the return duct also. Ours was under the bed.

We too have the basement A/C in our Dolphin, and from time to time, have also closed off the bedroom doors, in an attempt to cool only the front of the coach. The reality is that, with the A/C intake under the master bed, the air is drawn under and over the closed doors, and the back bedroom will eventually become the same temperature as the rest of the coach. Want proof? Turn on your A/C, and close the bedroom doors, and stand in the bedroom, next to those closed doors, and feel the air movement. These days, we don't even bother closing those doors.
See ya out there!!

When I want to maximize the front cooling, I just close the registers in the ceiling in the bedroom. Works good.

A/C units should not be run with any registers closed nor doors closed, you are restricting the air flow and reducing the capacity of the unit.
If you are having problems, I would start by inserting Vent Cushions and Window Coverings

If that were true, I would think that all RV manufacturers would save a bunch of money by putting in non-adjustable vents.
by adjusting vent openings you are decreasing volume in certain areas and increasing it in other areas. certainly RV HVAC systems are not designed with the exact register area for the specific AC unit. in that case they would require different AC units for 24 ft, 28 ft, 34 ft, 38 ft, etc. RVs.

Bumpyroad, the vent info has been relayed to me on more than one occasion. Just because they are adjustable, doesn't mean they should be shut off. The same info is appropriate for S & B home central air.
