The factory build of the Winnebago Vista 27N limits the door swing to 90 degrees which can make it difficult to carry items in and out due to the close proximity of the full wall side on the other side of the door.
I was able to move the mount point of the door swing limiting piston and get the door swing improved from 90 degrees to about 110 degrees. It still clears the awning arm so that operating the awning with the door open does not cause damage.
The piston mounting plate does not quite cover some of the old mounting holes after the relocation. I just covered the exposed part of the old mounting holes with heavy clear plastic tape , but caulk or colored tape would work too. The door still closes and seals fine with the plate in the new position.
The OEM screws are self drilling and are screwed into aluminum so it is a pretty easy change if you have a electric variable speed drill with a phillips head driver. You also have to drill one hole where the pivot pin is pressed thru the plate of the mount point so the plate will sit flat on the door frame, you will see the original hole I am talking about in the 2nd photo posted here.
Here two photos , one of the improved swing and one of the relocated mount point of the piston.
