I made a small, but satisfying improvement to the refrigerator. My SMB's 'fridge has a small thumb latch that flips down to hold the door closed on the road. It works great, but...
Is it just me, or do others find themselves driving down the road and then suddenly thinking "Did I latch that door?" I swear it's like going on vacation and then spending the last week wondering if you left the iron on and will come around the corner for home and just see a pile of smoking rubble. So far, 99% of the time when I pulled over to check it WAS latched (and the one time it wasn't I got lucky and it stayed closed), but that's a bother.
My SMB has an RB 30/31 type plan, so the fridge can be seen in the rear-view mirror while driving, but the latch and the surround are dark, dark grey, so while you can *try* to see it, you can't really tell if it's latched or not. So yesterday I cut out a small "dot" of retro-reflective tape from a roll I had, and I stuck it to the forward-facing portion of the latch, which is visible when it's properly latched. Now a glance in the mirror shows me that it's latched (or that I had better pull over pronto!). I can even see it at night when there is an oncoming car (but it's not large enough to be distracting), or presumably if I shine a light backward.
When the 'fridge is unlatched the tape is completely out of sight.
I like how a small, "free" improvement can make things so much handier.
