as it stands now I beleive the Rhino is 56" wide. so its not rated for 50" trail. the only side by side I know that comes in at this is the Kaw. 610 utv. they are 49" wide at the tires & chassie. the latest ones have fender extensions that put them at 51". but the wheel track is the same as the older ones.
Pilots & Oddessies are said to 50.5" inchs so depending on the tires its in or its out.
