I gotta admit, for a 22" unit, that high off of the ground, if you had to refuel and it was loaded with meat, a door would probably seem pretty important.
For my 18" WSM's, the door is pretty much irrelevant. If I need to refuel, even if loaded with meat, I lift the chamber so I can refuel the whole ring.
I can't say the same about the 22" however, because when loaded there could be 60 to 80 pounds of meat in there, and the arm stretch around the 22" makes it more difficult to lift than the 18".
Of course, this looks like it is not as high of a chamber as the 22" WSM, so it may not hold as much weight when loaded, making it workable.
If you can get it all in one load though, I see no problems.
The kicker for me would be lifting it off and setting it on the ground while fully loaded with meat. If I knew that was not a problem, then I see absolutely nothing wrong with it.
