Look up Bosch CP4 failures. The Bosch CP4 in the TDI is similar(single piston version) to the one in your truck and very similar to the CP4 in the Duramax and Powerstroke. These pumps failed often on the TDIs due to poor filtration and water in the fuel. Most engines with failed pumps had signs of rust in the injectors(that were often destroyed when eating metal shavings from the pump).
Personally, I'd run a long oil change interval, 30k or more. But I'd change both fuel filters often with oem filters. Use it as an opportunity to keep an eye on the CP4, it'll leave shiny metal flakes in the filter housing a few thousand miles before failure. It shouldn't be an issue on this truck though if you keep up with the filters and keep the water out.
