It has a drain tube/tay up top that it will run off what ever side of your MH is the lowest.
EXCEPT:
If the amount of condensation is low enough and the sun is just hot enough it 'can' evaporate before it has a change to drip off. Which I have found to be on very rare occasions.
I would get up on the roof. I had a Class C that didn't drip the condensation. What we found was a lot of green water pooling on the roof. The A/C unit is heavy and sometimes it allows the roof to be lower there than the edges. Which means you 'need' to un level the MH to allow it to run off or end up with more problems.
I would also check your coils to make sure they are clean. Not clean = no evap and eventually froze up air cond. When I saw no condensation it was usually dirty coils.
BTW, what is a NTM 22-YO Ultra?
We must be willing to get rid of the life we've planned,
so as to have the life that is waiting for us.
