Howdy Rusty. Don't recall such comment, but the general consensus here is that...A. More power is better, especially in a bigger bus...and, B. All mechanical engines will be the least troublesome. Anything after 1994 will be loaded down with EPA mandated sensors, chips & computers that very few people can deal with. Even the factory techs. There are a ton of low mileage buses on the market simply because they became too costly to maintain very early in their lives.
