Hey James, thanks for reaching out. The Seaflo RV Toilet # SE52MR may be a good option for your 2005 Montana fifth wheel, but there isn’t a way for us to look up exactly which toilet model came installed from the factory or how much space your specific bathroom layout provides. Because of that, the best way to confirm compatibility is to take a couple quick measurements from your current setup.

The most important measurement is the rough in distance, which is the space from the center of the floor flange opening to the back wall. The Seaflo # SE52MR requires a 9-1/2 inch rough in. If your existing setup matches or exceeds that measurement, the toilet will fit without issue. I recommend comparing that number to your current toilet before ordering.

If you take the measurement and it doesn’t match, or if you’d like help finding a model that fits your exact spacing, just let me know and I’ll be happy to help.
