Damn that is alot of reading. I only read it because I own a Cherokee. I am sorry that you feel that way about yours but sounds like you just got one that was not taken care of. My 96 just rolled 192,000 miles this weekend on my trip to NC. Yes it rides a little ruff but it is a straight axle 4x4 so I don't expect it to handle like a small car. I would guess that most of the ball joints in the steering system are shot since you have a lot of play. I changed mine to Heim joints and it is a lot more responsive. As far as the gas milage, again I guess yours needs some help. I put a header, exh, intake, and elec fans on mine and when I drove it to FL I got 20 mpg with the a/c on. The motor is crude but I pulled a 3000lb camper 600 miles one way to MO and back with over 190k miles on it. Finally, I will have to agree on the interior, my leather seat are pretty comfy but the dash is crude as hell. I guess that is what you get with American cars.
I guess what I am trying to say is not all are bad just maybe the one you got. I know people that have ****ty Hondas, Toyotas, etc. Later.
