Narrative:

I landed at grb in the middle of the night and unloaded my cargo. While I was getting my clearance through ZMP, an airport vehicle pulled onto runway 24 to check lights. I then taxied from the ramp to runway 6 for departure to osh. After a run-up, I made a call on 118.7 (CTAF, tower frequency) that I was departing runway 6 with a right turnout to the south. Somehow the call was not received, and upon reaching rotation speed, I saw the truck approximately 4000 ft down the runway. I made the choice to take off and reached grb FSS, who told me they never received my radio call. Next time I could make a closer check of the runway environment, and doublechk radio frequencys and that the radio is transmitting.
