Seal design for a square drop rear door?

I'm building a 5x9x4(H) square drop and have mulled how to do a rear door for about a month now.
Top open hatch: Top of trailer is only 5.5' above the ground so it will be very difficult to stand under the hatch to do any cooking.
One large side open hatch: Challenger Doors/Vintage Technologies has a 48x40 door, but it only seems to work for a rear storage space.
Van style doors, (like Levi Mize's design) seem to be the way to go though!
So - how does this design look? Using regular RV style trim w/ hatch seal.
