Bob, you ran 2 awg wire, was this due to extreme length or did the code guy just add 20+30+50. I will have to check with the AHJ, cause if I have to run #2 I will put in a 100 amp sub panel on the interior side of wall. Coach is a sub panel with a diverse load, and the other 2 outlets are also a diverse load. 50 amp conducter on a 50 breaker is still kosher. And a whopping 12 kw of load.
Didn't ask the code guy. 100 amps equaled 2 g wire as far as I calculated. length from the panel was 12 feet or so I think...  There is one 240v 50 amp breaker, 1 120v 30 amp breaker and a 20 amp gfci breaker. So the max load could be 100 amps so I sized it for that. Might be overkill, but they didn't have any 4 awg. Have a 100 amp breaker at the main box feeding it.

Thanks guys for all your wisdom and input. Being the cheapskate I am, I think I was being penny wise and pound foolish. Bought a 100 amp subpanel with 24 spaces for the the front of the coach house  between the garage doors that will serve the original garage that was 100' from the meter, the exterior RV outlet combo, any welder, plasma cutter or tools to be used outside mainly, the new ground level washer and dryer (it's in the basement now) but soon to be located in an infill structure between the coach house and residence. Maybe an ATS and new circuits to run the freezer and fridges that are now 40' away, and of course the gas furnace that's 100' feet away and sump pumps. 120 v backup generator from the coach would require some serious fore thought about about which leg to the sub panel to use, along with the neutral coming from the main  unenergized 200 amp panel.  Definitely a ? For my EE expert friend.
