f1100's recommendation to go to the FA section and read the winterizing post will cover you. The big part is winterizing the water system.
You may want to clean the canvas on your bunk ends and wipe down your bunk seals if they are dirty before storing it away for the winter. As always, make sure the bunks are sealed properly with no cloth pinched in between the seals. I put some powdered graphite in the latch locks.
That's about the only difference I find between a hybrid and a TT.
As with any trailer, make sure to get up on that roof and check the caulk. While up there, take a look at the orange lights above the front and rear bunk to make sure they are sealed and caulk as needed.
