One thing that has not been mentioned here, where will the truck/bed live? Garage queen, always outdoors, hauling things, etc. It matters. If the truck will spend most of its life indoors and only sees sunlight or car wash occasionally, use any finish that gets the appearance that you want. If always outdoors, then your choices become much more limited for a long term durable finish. I visited Mar-K recently and looked at the wood finish tests which are still ongoing. The black painted Behr over POR is showing some weathering but still appears to be a solid finish in the test. These have been continuously outdoors in the Oklahoma weather since about 2005. I don't remember that any other finish in the test lasted more than a year outdoors, most were failed within six months. I know the Mar-K tests were limited and that there have likely been technological advances in finishes and techniques since 2005. If there is another finish that has shown good outdoors results, this would be good information to know. Hambone, I would be particularly interested in the success of your teak oil finish.
