Are We There Yet?
Most automotive supply houses have window channels but for a vehicle they are smaller than the RV channels.
After looking/ calling all the web sites you supplied, I still came up with nothing.
Finally found a RV supplier ParKin. They were very helpful over the phone but were out of what I needed. Found out the Pace Arrow windows are made by Attwood. No body else knew this. They did have 4' of the window channel, so I'm going to try to get it installed and stop some of the leaks till they send me the right amount.
Horace, Sorry I didn't get to reply to you post sooner. If you want to contact Atwood directly, they sell to the end user. Here is Sue's contact information.
