Tung oil for bed wood?

[62lwbc10]

Hello all I just received my brand-new Bed wood from mar k. Went with Oak. I'm now starting the task of figuring out what kind of finish to apply. Durability and resistance to weather is not that much of a concern to me because my truck will likely never see any kind of precipitation. Someone mentioned using tung oil rather than the typical Marine or spar varnish. Wondering if anyone has any experience. Thanks in advance
