Shop vac arrived yesterday on schedule. However, it's raining today, so not a good time to test drive it on the KK. Forecast for the rest of the weekend is better, so I'll likely test drive the vac tomorrow afternoon.
Thanks for the tip, Cookie. One of the nice things about this particular vac is that it's designed to handle warm coals, too. Not that I plan to test it out intentionally; just a nice "safety net" feature.
