Agree with those who say private CGs probably no problem, even on the East Coast. Be aware, however, that many CG's in colder climates like the upper Mid West and Northeast close down before Thanksgiving due to their water services being above ground and subject to freezing Nov - sometimes as late as late March. State parks and other government owned camping areas are much less certain. Might want to become familiar with www.rvparkreviews.com for some specific info posted by RVers who have been to different parks around the U S and Canada. We find it very helpful. Could also check Reserve America. Often there are pictures of specific sites in campgrounds present, as well as written descriptions of width, depth, slope, etc. You can also reserve a site through this site as well.
As far as driving a big rig in the Northeast - can be challenging, to say the least. Older roads tend to have narrower lanes, and many in this area have numerous overpasses that, at times, just aren't high enough for taller rigs to pass under. We have a 32' MH with toad and DH, who has been driving RV's for over 40 years, will not travel on some roads in some places because of the volume of traffic and what he calls the "harried pace" of the drivers. BTW, he drove large trucks in the Army and is skilled behind the wheel. For instance, we NEVER go through Richmond on I 95, or take that interstate near Washington DC or Baltimore. We take I 295 from Petersburg to north of Richmond, then pick up U S 301 around exit 104, reconnecting just before the Delaware Memorial Bridge into NJ. Takes a little longer, but a much more relaxing stretch of the journey. There are many circumstances around the country where this can be done. Have fun, safe travels, and take your time!
