I visited the Torklift shop in Kent a couple of months ago, and will probably go with the Stable Loads and a Superhitch. At that time, I hadn't yet decided on a TC, but now that I have, I'll make another trip down to discuss in greater detail what I need....also to talk to them about how to fit my spare under there....I like your onboard air...sweet idea.
My OEM tires/wheels I'll keep for offseason. It's not my daily driver, so I'll only have my teeth loosened half a dozen times a year.
Sorry to hear about your wife's vehicle. I had a lemon once...1984 Buick Riveria...worst POS I've ever owned.
Cheers
