Red Diver,
Welcome to the forum and congratulations on the "new" rig! We also have a 2008 Classic 30'...same pocket doors on either side of the head area. Sorry to hear that you've run into an issue with your new baby.
A couple years ago our Granddaughter and friend were 'playing" unsupervised in the trailer when suddenly one of the pocket doors no longer had full travel. Nobody could explain what happened and of course "they didn't do it". After several unsuccessful probes, lifts, taps, pushes, shoves and grunts inter-mixed with several kind words of encouragement our "fix" was to disassemble the wall trim to access the area.
The pocket doors run back and forth on a roller system hung from a metal track. The track is simply screwed vertically into a overhead wood supporting member. In our case a screw securing the hanging track came loose blocking the roller assembly from moving it's full length of travel.
You maybe able to use a bright light source and long thin tools to probe the path of the track for obstructions.
Careful disassembly of the bedroom side wall trim allowed me to open the area up and find the problem. Tightening a loose dangling screw securing the metal track solved the problem.
Key words here, carefully opened up the area, as in slightly pull the bulkhead wall away from the door structure so I could see what was causing the issue.
The forward pocket door has bathroom on one side and fridge on the other. That'll complicate things for you trying to open up the wall to see.
Ours was the rear pocket door...shower on one side and bedroom on the other. Lots of screws, trim and valance in the bedroom to loosen and remove. Once done we could to pull the upper portion of the bulkhead backwards and get a view, find the problem and repair. Careful reassembly and its as though it never happened. Total time about an hour to do the rear one...your mileage may vary with that front one.
Here's a link to show what the hardware looks like...it's not a replacement...just gives you an idea of what you're dealing with:

That's what happened to us...Good luck with your "baby".
