OP, FWIW consider financing a new truck. I know you said you only want to spend 10k, but consider the option of spending a few hundered bucks a month for a brand new truck, versus plunking down 10k on someones old worn out workhorse with 130k miles. With the used car market at an all time high, I don't understand why people don't take advatage of deals on new cars. Certain MFGs are giving away trucks with rebates and financing deals.
You can use me as an example. I bought a new 2010 Nissan Titan around 3 years ago. I paid around $30k OTD. That was ~$10k off sticker, a deal that you can still get today. Galves says the truck is currently worth $26,500 with 30,000 miles on it. If I were to sell it today I have no doubt I could get $26k for it in a heartbeat. So the truck cost me $4,000 over 3 years if I let go of it tomorrow.
So why spend 10k to drive a used truck, when you can drive a new one for less?
