"I got my eye on a UniMog fire crew truck up the street"How are they with spare parts?
Check Pinzgauers. They are, in general, much more nimble and easier to live with. Not exactly your Range Rover Vogue when it comes to luxury, but they climb like a goat. Depending on configuration, it can almost be a practical grocery shopping vehicle. And with sizes of SUVs these days, it is (comparatively) not even that big.
