M101cdn2 trailer wheel interchange?

[James Hybicki]

I have a M101CDN2 1/4 ton trailer and do not have a spare to carry when using the trailer.

Has anyone come up with an interchangeable wheel that will work in an emergency since the correct wheel is so hard to come by here in the U.S.?

I would prefer not to go the adapter plate route to switch to a common Jeep or other brand rim.

You smart guys who have done the dance with these wheels probably know the solution and I don't want to "reinvent the wheel" so to speak.

Thanks in advance for any help.
