How to access drain hose storage when TM is collapsed?

I know this question has been raised and answered before, but I can't for the life of me retrieve the thread. Sorry to start all over again. We're about to embark on our first TM camping trip, and we need to know!

With the trailer folded down for traveling, the rear half of the roof sits on those two rubber bumpers and blocks access to the plastic cover over the drain hoses.

I must be missing something. When you get to the dump station, how do you proceed without raising the rear half of the shell?

Thanks for your patience with a newbie.
