You're not really supposed to comment on the condition of a truck in the for sale section so that's probably the reason for lack of feedback.
If you sanded up the bodywork and had it painted, I could see you hitting the asking price or in the ballpark. People want turnkey trucks for $11K, not projects no matter how small. If it was diesel or had a/c it would probably be gone already.
My $.02 that will probably be deleted for breaking the rules. Oh well! Good luck and hope it sells!
