Welcome!
Be aware that two A/C units will require more electrical amps than your TT is set up for.
Many Minnie owners have purchased the TT with the 2nd A/C installed at the factory and found that the trailer is not able to run both A/Cs at the same time. Even though WBGO continues to state that it can be done.
Here's a thread on the topic here and you'll see the problem:

It really seems that Winnebago is expecting owners to run one A/C in the living area during the day and the bedroom A/C separately for sleeping. Well, that's how it seems to be designed, but not what they are claiming on their website.
There are plenty of travel trailer owners of all brands that have modified their TTs to 50-amp service so that multiple A/Cs could be run at the same time.
Best of luck on this project.
