Hey Mike,
I was unable to find the rough-in requirements for the 210 but you can measure your rough-in to see if the Dometic 310 Part-Timer RV Toilet # DOM57FR would fit. The # DOM57FR requires 10" of space from the flange bolts back to the wall. I've attached a little diagram below showing how to measure for the rough-in as well.

Hey Mike, were you able to measure the rough-in space for your Fleetwood Discovery to see if the Dometic 310 fits? Once you have that measurement, I can help confirm whether it’s the right match.
