I have been trying to find a schematic/blueprint of what it actually looks like under the roof vinyl before I try exposing it.
I'm wondering if anyone has had any expirience in dealing with this and how much of a pain in the butt it is. I don't have the original lighting housing that was installed when the coach was produced. The guy I bought it from ran LED lights from front to rear and glued up velcro stripes to hold light covers in place. Its a 38' 1993 HR Navigator spartan 300alli xsmn diesel pusher w/ 8.3 cummins. Thanks in advance for any help.
Why don't you post some pics of your interior ceiling?
What A/C units do you have (make/model)?
In the meantime, have a look at this:
A/C Ductwork collapse and rehab
In my case, the lack of flow was caused by ductwork collapse at the airboxes. The ductwork that runs the length of the coach was fine.
