Anything older than about 1991 will have a carburetor instead of fuel injection. Carburetor's work fine, they do drink a little more fuel than injected models. Expect about 6mpg on carbureted, maybe 8mpg on injected.
The suspension is the same on newer as it was on the older coaches. Chevy P30 chassis are weak while the fords are a little stronger.
Older coaches seem to be built better, but you also get no slides which is a desirable option. I love my slide, and now that i've had one I would not be without one. Just a few things to kick around.
