The wheel covers & tires tell what chassis it is. If it is truly a 95 chassis, then it is a throttle body 454 on a Chevy P32 chassis with electronic 4 speed OD transmission. If by chance it has a 96 chassis, then it is a port injected 454 Vortec engine. It will have air bags in the front springs that are subject to failure and the infamous P32 bell crank on the steering linkage. Check the exhaust manifolds closely for leaks and cracks. They are a high failure item. All the for mentioned items have after market cures but are expensive. You may have found a nice coach at a decent price.
