So you're seeing injector issues and still think the cheap stuff is fine? I've seen the same thing happen with off-brand DEF causing sensor problems and clogged filters. That bargain jug might not meet the right purity specs, and even a little contamination can mess up the SCR system. Saving a few bucks on fluid now can lead to a huge repair bill later. It's just not worth the risk for the whole fleet.

Oh please, a six foot fence is just basic privacy. Does he want a chain link fence he can see through while he's grilling? Tell him to plant some ivy if he wants it to look friendlier. My last neighbor complained about my bamboo screen, then asked for cuttings a month later. People just like to talk.

Honestly, I'd fix the old one. Those older KitchenAids are tanks. The new ones just don't feel as solid. You can find the gear online pretty easy. It's a common fix.
