You might want to try dropping it, just to make sure the mechanism hasn't corroded. I realize you're in Texas, but it's still worth checking out and shooting some chain lube or WD40 in there. You don't want to find out at 10PM on a lonely road that you can't get your spare.
Also, any time you order parts for it, make sure you specify that it's Stow 'n' Go. It affects a lot of things on that vehicle, particularly undercar stuff.
