Rudy, just cruise around on Google Earth and check it out. You will see pullouts! Don't forget to try different years -- some of the photos are in the winter, some are on weekdays. The photos taken on weekends are pretty useful -- you can see which spots are "big rig" friendly, and which are not, just by the types of rigs in the image.
For those of us old enough to remember the days before the internet, it is mind-boggling that I can sit in my living room and fly around the forests, traveling from year to year, looking for campsites.
