Not really sure what unit you are asking about. A 5th wheel, if you take it to a frame shop will be able to somewhat aligned the wheels. If I remember its more of a total axel front to back kind of thing. Yes the wheels on the Minnie can be aligned you just need to find a shop that can handle it.

Have a shop replace your spring shackle bushings. Worn bushings will cause weird tire wear, happened to me. Stock plastic bushing wear out almost as soon as you put new ones in. Look at replacing with bronze bushings (but you have to grease them frequently) or NeverFail bushing from Lippert. And replace that tire!
