uneven tire wear

On our 2955RL Montana 5th wheel ( 2006 ), I noticed that the left rear tire is wearing on the inside. I suspect possibly a loose wheel bearing. Any ideas?

Check for a bad tire...that's what mine was.

Probably a broken belt.

You may have lost positive camber on that axle allowing the tire to lean in at the top. Just to get an idea as this is only ballpark measuring, but put a level on the outside of the tire straight up and down ... the tire should be leaning very slightly out at the top assuming your sitting on level ground.

Dieselguy has hit the nail on the head. Sounds to me you have a camber problem and you could have an alignment problem also. I had an alignment problem on mine when I had a new axle put on down in Arkansas and took it to an alignment shop that does big rigs and everything is good now!

Towing with an axle that has a normal working brake assembly on one end, and a reduced efficiency(for instance, grease contaminated) or non-functioning brake assembly on the other end will skew that axle out of alignment during medium to heavy braking conditions. If towed in this condition for enough miles, it will cause tire wear problems. Throw in some leaf spring shackle hole out-of -round wear, and nylon bushings that are shot, and the skewing effect is increased.

....ask me how I know!

After I fixed my single, non-working brake problem, and installed the wet bolt kit with the thick, heavy duty shackles, my tire wear issue went away.

Not saying that this is your problem, but it is one more thing to look at for the cause of your odd tire wear.
