I would not compromise. Even bus air is becoming obsolete because the systems are so old when they do go no one can fix them when you need it. I had 4 calls this summer from guys on POG needing help out west that no one could help them.
I have a Liberty friend with an 07 who lost his bus air and CA's on his way to Montana. Liberty Chicago told him we are not working on them anymore, he ordered a new Marathon in AUG.

If you run out west across the deserts in the summer you can't stay cool with CA's, impossible. There's some old timers on here right now saying ahhh mine are fine or the roof airs are noisy. BS.

We have a couple guys on PC who have had it with CA's and have cut holes in the roof and added roof airs. They are very resourceful and the 1st bus is working great. I'm sure they will get feedback from Monday morning quarterbacks but I give them alot of credit. They had enough. Anyone who tells you I can get right in to so and so to fix CA's is lying.

We'll see if any of the guys that called me jump in here.

Later
