When we first got our TM our bed supports kept popping out of the rear tracks. I cleaned them off, applied some lubricant to the plastic guides, and adjusted the gap in the washers until it was just wide enough for free movement. Yours look like they might need to be replaced, the factory can send you some. In the meantime, if you clean & lubricate them & adjust the washers, it might help some. It's very annoying to get ready to leave and have those darn things pop out. Pushing the beds slowly in from the center while another person helps the arms slide along should help too.

Hopefully someone else will chime in about your other issues.
