Not necessarily.
I do mine totally different than most.
I go between the side walls.
Heres an old answer I gave on the subject earlier.

Ha ha hahahah
You doing anything special for a seal on the sides of the hatch?
I do, but I can't find pictures of it at the moment.
I always run the outside molding through the hatch area, a continuous run, front to back and build the hatch area in about 3" each side.


Another trailer but maybe a better view.

I run a second insert molding on the inside of the hatch on the body of the trailer. This becomes the seal for the hatch.
I make the Hinge, and I use an offset hurricane hinge" 2/3" shorter than the distance between the 2 outside moldings which is a 1 1/2" on each side overhang. (+-)
This gives the water a 1"(+-) channel for it to escape.
For water to get into the galley it has to run down, make a right or left turn, run up hill and jump over a 3/8" barrier.
Be at one with the gravity! Waters like talkin to a teenager, no matter what you say, it'll do what ever it wants. And then say Duh!
Photos to come.
Yet another trailer.
The troth the water goes through

This is the old way I did it. Now I run the upper part of the hinge 1 1/2" over the edge of the lid as in photo #3.
Happy Trails
