I wasn't sure what you meant by "pre-attached" bunk ends. I'm thinking you must have the bunks with the "un-attached" canvas. If you're Roo had one year newer, you wouldn't have been able to do what you did, so yeah, you lucked out there!
On the fridge: If I were you, I would have swapped the fans over to the new fridge and installed a switch to turn them off and on. I suspect you old fridge ran better than you're new one will (quality seems to be declining). You might be wishing you had those fans!
