Hey, I just got back from Pakashkan on Tuesday this week.
Graham road is plowed, at least as far as Pakashkan road. Pakashkan is plowed from the Graham road all the way to Suka.
You will easily be able to drive your truck all the way to the public boat launch on Pakashkan.
there is still a half foot of snow up there and no grass to be seen, its still winter up there.
cheers
