Well, the main reason to call it something else it to avoid confusion - and this is more of a cameo than a main-role.
Chris: I was actually thinking maybe something along those lines, but we were actually going to have modular cargos for the Drayman - one of which would be the Diligent. Those two models are pretty much identical in every way - except the sort of cargo they're hauling. Don't think it didn't cross my mind, though...
t.c.cgi: The reason it looks a bit like the Clydesdale is that the SWC Drayman model has harvested some of the model bits from the WC2 Clydesdale model. It's really just a re-arranging and re-texturing of those parts. I could post a comparison, if you'd like?

Diligent is the proper spelling of the word, and we use it in a lot of our materials (from the ships database to the current front page poll), but I double-checked and it's two L's in the game. Halcyon's dialogue speech, your Hornet's nav map and the in-flight targeting computer all spell it Dilligent. The Confed Handbook refers to the Movie's Errant as the Diligent though.
