2000 Ford F350 Superduty 7.3 Diesel Dually w/ Low Profile Hauler bed

The truck is very solid. new glow plugs. glow plug relays. intake. back pressure sensor and tube. All 6 tires are new less than 2000 miles. Since I bought the truck 2 years ago. I spend $1000 at dealership to replace tie rods. ball joints etc steering components and alignment. spent $750 on AIRAID intake and 6-position chip (w/ high idle). $350 on Banks catback exhaust (w/extension. will come with the truck). $400 on brakes and belt/pully. $1000 on brand new General Grabber tires mounted and balanced. $1600 for the tune up done 2 weeks ago and a lot more misc items. That's more than $5000 I spent on the truck in less than 2 years! And I didn't even drive it for 10k miles! I'm selling it just because I don't need a truck this size anymore and I need money to work on my other cars now. Low profile hauler bed with LEDs. Price is $7500 obo. please give reasonable offers. no trades.
