That hatchet method scares me. It never occurred to me to take a hatchet to my trailer. LOL. :-)
After taping off the lines to cut, I drilled pilot holes and used a jigsaw with a good metal blade to cut from the outside. That also allowed me to cut the studs at the same time and wood backing as needed. Seemed to work well for me. All simple tools readily available.

The hatchet was literally a couple of very light taps and I was through (made me realize how unsecured an enclosed trailer really is). The new opening allowed me to get my shears into the metal with ease.
My concern in using a jigsaw was the vibration of the aluminum with a 15" span between ribs. One point to mention is that my interior walls were completely down when I used this method.
