Just some advice for you on the truck as a truck guy and a contractor: I've found the best bang for your buck without the frills is a Dodge Ram. For 10 grand you can probably get yourself an '04 or even an '05 quad cab 4x4 with a little higher miles. If you are crazy and have no schedule, look on craigslist in the Tampa and Orlando areas. For some reason they are cheaper in Florida. Don't buy from a dealer, you will pay tons of mark up. Look for something with 100,000 miles and in good shape and you can snag a great truck. Toyotas are awesome but just run a lot higher in price as well. I have a Dodge Ram with no frills at all and got an insane deal on a newer one. Good luck bro!
Oh, and P.s. you probably won't find one for 10k and good mileage until you buy an older diesel. 4x4 with good gas mileage and a bigger engine doesn't happen except with a diesel.
