Your mods came out real nice! The magnetic holdbacks looks like it works well and looks good.
I had a similar problem with my bathroom door making contact with the coat closet door so I added a very small size rubber bumper to the door. While traveling the fridge door came open hitting the rubber bumper putting a dime size hole in the fridge door panel. Upon inspection the fridge door would not been able to make contact with the door knob but not for the rubber bumper.
After seeing a rubber stopper installed on a FR unit on the lot I added one to my unit. It's not as pretty as your but does the job. Surprising I don't even notice it and I really thought I would. Cost about $4. It's been a while so now I don't notice the small hole in the panel either.
Great choice for "Living within my means" and camping for one...
