First off, apologies for all the flack you've (unnecessarily) caught in this thread. You bought a beautiful, UNIQUE truck and you should be proud of it.
Might it have some issues? Sure. Have you researched the A/C condenser issue? GM has had more than it's share of issues with them, there's a TSB that details it. Basically the drier welded to the side of the condenser wasn't welded enough, causing it to flex and crack. There's an updated part from GM, and the aftermarket units I've seen also seem to have updated their design although the fit and finish leaves much to be desired.
Second, the belt-driven vacuum pump for the brakes. Much known issue. I forget which model year they "fixed" this, however when it does fail it sucks engine oil up and into the brake booster vacuum line and eventually into the booster itself. GM's recommended fix is to replace all 3 parts: vacuum pump, line, and booster. Personally, I see a loss of vacuum assist long before any oil gets sucked into the line. There may be a recall on this, I can't recall.
Other than that, they're great trucks. Your truck actually reminded me of my first pickup: an equally odd-ball 1991 F150. It was a regular cab, long box, Lariat package truck. However, it had the straight 6, the 4-speed non-OD manual trans, manual transfer case, auto locking hubs, dual shock front suspension, full gauge package but with manual mirrors, windows, and locks, and 250 rear leafs from the factory. Someone went goofy with the order sheet on that one!
