I have a 4Runner (95 Limited) which I drive in the winter. It's a little tight on me (6'3") but really not that bad. Toyota's are known for their reliability and I haven't had a whole lot go wrong with it in 90K miles. It's even got me thinking about a big Lexus sedan the next time the question arises. I have no complaints with the ride, even with knobby tires, and my freinds that own other SUV's have commented on how smooth it is. My biggest beef with the truck is the lousy gas mileage (14 MPG) and small gas tank (@15 gallons) makes for short range compared to my 300SDL.
My only other suggestion is that you buy a utility trailer regardless of which vehicle you ultimately end up with. I am constantly doing DYI projects, like building my son a tree house (actually mini-Taj Mahal) and the trailer is invaluable for hauling plywood, etc. that you wouldn't want scratching up whatever you buy. I even have a trailer hitch on my Mercedes.
