This is a luxury coach, flagship in 2006, 37,000 miles. It has the Detroit series 60 pre-def million mile 515 H.P. engine. You don't have to buy the extra diesel exhaust fluid (DEF). The complete spec. sheet is in the photos. The tires are in great shape and the batteries are almost two years old, new microwave convection oven, new led lighting. We are in our 70's non-smokers, looking to buy permanent in Fla. If we were younger we would keep it.  If you want to call me feel free. Gary 423-782-6354 or 423-782-7815. We are in Fla. now but will be in Tenn. in April. Thanks for your time. The price is negotiable.
