Reinforced toilet flange

Hello,

I found out on our last traveling adventure that the right hand side of our toilet flange broke rendering our toilet wobbly. I have since returned and removed the toilet and flange and set out to find a new one.

I know I can get threaded flanges online (no local plumbing supply houses seem to have them), but all the threaded flanges seem to be only for RV's and trailers, which IMO are cheaply made plastic. I'd love to find a metal reinforced threaded flange like they sell in Lowe's that would thread in the tank, but the only metal reinforced flanges are the glue on style.

If these things just don't exist, I even entertained the idea of modifying my replacement flange with an aftermarket "repair ring" that you can get at Lowes. I'm just trying to come up with a long term solution here. We've only had the camper for just under a year and we've already broke the flange, I'm not trying to make replacement of a toilet flange an annual ritual.

Thoughts and advice are appreciated.
