You could try this, might not take into account the unique paint. Don't pay attention to comments about leather or glued trim. If it's original and in exceptional condition, that's what matters, not someone's preference in accessories and appraisal which are meaningless having no basis.

Put together a sales brochure on classic trader that matches the condition of the truck. Spotless detail from head to toe. Might pay to work with someone that can market what you have. Quality photos with a proper background. A professional listing pushed in the right markets could dram top dollar. Good Luck

 

Myself, I would keep it. Every DIY'er needs a "working" truck. Talk is cheap and the ones interested in buying are the bargain shoppers looking for a deal.
