Since my dash AC doesn't work and I'm not sure I want to try to ever make it work (they have a reputation for unreliability though it escapes me why that should be inherently true), it might make sense to remove the evaporator to reduce the air restriction it creates.

Another thing I noticed on this trip is that the vertical seal on the front sliding window leaks a bit and is pulling air out of the coach. I need to put more effort into making the coach more air tight since improving heater performance can be worthless if the heat doesn't stay where it belongs.
