You could buy a really nice mid-'90s Chevy 2500 or 3500 for under 10k. You'd have more power, cheaper repairs, better to tow with, and a more practical truck.
If that was a personal vehicle that you weren't going to use for work, then I'd pat you on the back. I don't really care for that truck, but if you pay for it yourself, then you earn my respect.
But if you're going to use that truck for landscaping work...good luck.
