A couple other things that come to mind that may or may not be an issue to you.....

Powdercoating is electrostatically applied (bare metal) so panels would have to be as straight as possible without any fillers (bondo). If any body panels ever got damaged, you may have to replace the entire panel no matter how small the damage is unless you are very good at metal finishing. The whole panel would have to be powdercoated again and I would wonder how well color match would be.

Automotive paints have UV protection in them and I would wonder the same about powdercoating......will it "chaulk up" over time due to exposure.

Just some thoughts that come to mind with my limited knowledge of powdercoating.

That said......it sure would be as durable finish as you could get short of bed lining the whole truck!
