If I may add a suggestion.
Start off by parking at the cross river state wayside and hike on up from there. Pick a site on the cross river as those 4 are some of the best on the trail. Wake up on day two and hike to the Caribou river multi-group which is 12-15 mile hike depending on where you camped the first night. On your last day, wake up and hike north to the sugar loaf parking lot where you could have shuttled and left a car the first day.
I actually drove by the sugar loaf campsite Friday night and the creek there was raging. The snow "should" be gone by next weekend and it would be such an awesome sloopy time to be on the trail.
