hey, im creating a new mission for my group which will be set on a war torn planet with them skulking around on the battlefield. now i found it disappointing to discover that there are no rules for vehicles anywhere and i would like to enable players to use some of them (like chimera and maybe sentinel). so, you have any ideas on how to approach this issue? my main concerns are vehicles resistance to damage (armour) and their speed.
vehicle stats?
Well, it seems I'm not the only one to want vehicles for DH. There is a free download PDF called Apocrypha. There are several threads throughout these boards with a link to it. Enjoy! 
found it already with help from the blessed brother google. thanks all the same.
Tattered Fates also has a sentinal in it, with different stats, I think those will be akin to the new stats promised to us in Rogue Trader
