I did the same mod but I had the weight of the pots and pans always pushing the door open. I found a twisting lock at WestMarine that was made for boat cabinets. It hasnt failed so far...
Now if I can only find a SECURE way to keep the fridge closed other than velcro. Nothing like pulling up to your spot and finding all your food and cold beer sloshing around the inside of your camper!
Good heads up on the drawer. So far fridge door hasn't opened, but some creamer fell over in fridge and leaked out. Messy!
