To notch or not to notch wall: Galley hatch question

I am still in the planning phases of my teardrop (planning to use the generic benroy as a starting point) and have been reading every available post regarding construction do's and don'ts on this site and others. I have encountered at least two builds where the builder did not notch the side walls as part of the galley hatch construction.
This peaked my interest and did additional research. On http://www.teardroptrailerparts.com/Hinges___Aluminum_Trim.html, HT05 and HT06 descriptions indicate that there is no need to notch the side walls.
So will I get myself into trouble if I don't notch the side walls? Of course I must ensure that the appropriate gap at the top and bottom of the galley is maintained so that the silly thing will open and close appropriately.
Your thoughts?
Thanks....
