2005 Silverado 2500

Bought this truck on eBay from a seller in Maine. He did not list the truck truthfully and because of that I'm not wanting to even keep the truck. I will be honest in the description since I don't want the buyer to be as disappointed as I was when I got the truck off the semi from the transport company.
2005 Chevy Silverado 2500 HD extended cab work truck. This has the 6.0 with rare 5 speed manual transmission. 4x4 that works. Previous seller said he bought it off a 75 year old gentleman that used it to pull his horse trailer around the county fairs in Maine. Since I have had it I've stuck 150 miles on it. The interior is in really good shape. The headliner though is coming down by drivers side. Previous owner had glued a silicone tube 16 inches long on door frame in this spot no clue why I ripped it off. Missing interior light on passengers side. When I got the truck the transmission was broke the bell housing was cracked in 2 spots. The transmission was replaced with a rebuilt the seller is supposed to get me paperwork giving a 3 year warranty on the tranny. Bell housing was also replaced. Transmission now shifts fine all work was done by Barnes transmission in Bismarck ND. Do have the reciept for installation. Previous owner bought tranny and bell housing don't have the reciepts on those. A/c doesn't work Chevy dealership quoted me 1200 to fix. Is a hole in the display for the gauges all gauges work. No check engine lights on. Engine runs good don't hear any missing.
ExteriorBody has about 5 dents biggest one is in drivers side side rail corner see picture. Does have scratches especially on the hood probably at least 6 to 12 tried to take a picture of this don't think it will show up good. Tires will need to be replaced they are mismatched and drivers side one is low on tread. The frame is the reason I'm selling the truck it has heavy scale I've pressure washed it twice and got most off with the pressure washer. Body has no rust spots so I'm confused why the frame is so rusty. Refer to pictures. No spare tire. Lenses all look like they leak water. Has gooseneck ball and hitch. Wired for trailer brakes have not tried them yet.
Doesn't pull or no noises now that the tranny is new. The title is still in the previous owners name I don't want to change it because I'm already going to be losing enough money on a truck I drove 150 miles. If I can't get enough for it I'll just have to keep it and hope for the best. Beware of any private sellers from Buckfield Maine I can't believe someone could be so dishonest. I'm comfortable with any test drives or if you would want additional pictures or have questions I would try to answer them to the best of my knowledge. I will be out of town Thursday till Monday night but can answer questions. Full payment is needed in 7 days. Happy bidding
