How long have you had it? Does everything work? Is it fully stocked with all tools, and tooling?
Also a realistic consideration is, what did you pay for it. You must have had an idea what it was worth the day you paid for it.
Why do you want to sell it? recoup your investment, profit all you can, make $2000 for your time and work.
I never understand when someone asks such a simple question, with no details.
If you just looking for offers, I'll might give you $5000.
Those trucks are far from practical to work out of.
