Hello and welcome!
Unfortunately, Travel Trailers (of just about all brands) don't get much in the way of detailed operators manuals. Conversely, Winnebago motorhome owners get tons of printed and even online resources.
There are lots of Micro Minnie owners here that can fill you in on most any details you need. And, many have reported that if they contact Winnebago directly they can get emailed diagrams of wiring, plumbing and such.
