Dodge Ram Van wagon 3500 15 passenger van

Exterior - Body is straight. There are several dents, primarily on the back corners which can be seen in the pictures and the bumper is bent. Other than that there aren't many dents. The driver's side passenger running board is slightly bent. The paint job is in need of paint as can be seen from the pictures.
The seats are "pleather" and for the most part in pretty good condition. There are a couple areas that are slightly coming apart, but as a whole in pretty good shape. The ceiling liner has begun to come down as can be seen in the pictures but is an easy fix so I hear in which I didn't take the time to do.
I have owned the vehicle for 3 years. I purchased the vehicle with roughly 98,000 miles and it currently has 122,000. The vehicle was originally owned by the state of Oklahoma so I assume it was very well maintained. I have had the catalytic converter and the water pump go out on me both of which I had replaced. Air conditioning works. The air conditioning for the back seats is currently restrained by the fact that the liner is hanging but does work.
The check engine light is on. I never reset it after I got the water pump replaced. I just got done taking the van on a 600 mile trip and had no problems.
The tires have about 10,000 miles on them. New set was purchased about a year and a half ago. They all have plenty of life left in them and there is a spare tire.
