Glad you got your awning fixed up!
My "thing" is not as big or expensive -- the sewer cap. Not long after we bought the TT, I had to buy a new sewer cap because I forgot to put the original one back on after dumping. The replacement came with a neat rubber retainer / hanger (similar to a lot of car fuel caps).
Now, seems like every other trip, after I get home I find the sewer cap hanging from that retainer. No, the cap doesn't just come loose - I've got some sort of mind blank about putting it back on after dumping!
See you on the road!
