We were up in 2010 (August-Sept). Bugs were no problem at all. Since we were going up a little later than most, crowds did not exist.
You should be good if you have 7 weeks, especially since you live on the west coast. But it depends on how much time you want to stay in certain areas. We kept moving and we were gone less than 2 months from Pa.
All total we spent a little over $100 in CG fees. These were only the few nights where we either had to stay at a CG or thought it best if we did. Most all nights were spent nestled in large pull offs near the roads. Never had an issue staying in any of those.
We found decent cell phone reception near the larger cities and towns, but dont remember if we had verizon then or some other service.
I had my air compressor along and I carried a plug kit. I figured most flats could be temporarily repaired on the road by using a plug and then addressing the permanent repair once we got to a town.As it turned out we had no flat tires.
Overall the roads were decent. You will definitely hit areas of construction, and it it rains you can expect to have a brown truck and TC. The white will be gone until you find a car wash.
Getting fuel was no problem. We used the 1/2 tank rule for the most part. Fuel was expensive. We learned not to get it from the first station coming into town as they seemed to be priced higher. Usually it was cheaper once you got further into town. If there were no other stations, we turned around and went back to the first one that we passed. Towns arent that big so it was no big deal to go back.
If you ask, you will find that some of the fuel stations have water and a dump somewhere on their property. Most of them will let you use them free if you buy fuel from them. Most do not have a sign out advertising this service so it pays to ask.
