Some things to check when putting 2 aluminum wheels on each side of rear axle.
1. Are the mounting studs long enough for the thickness of 2 aluminum wheels?
2 . Does pilot hub of axle stick out far enough to properly locate wheel on center?
3. Will 2 aluminum wheels affect location of outer wheel be offset to far?
Your list outlines what I always understood, why the inner two rear wheels remain steel when using Alcoa wheels. If another brand can have all alloy in back, then I wonder if the alloy wheel is thick enough for weight of a motor home. I once found pictures of alloy wheels that developed cracks but I can't find them now.
Of coarse with finished alloy wheels, you loose the ability to rotate them, but I don't rotate my motor home tires because I feel doing so does much more harm than good.
