We finished a x country trip out West and to Alberta and British Columbia last year. Study the weather patterns. We took RT 10 West and then the Northern route I-40 on return due to bad weather from I-40 North in the Spring. We started from LA, though and not NJ. If you had the time and wanted to, take I-84 W to I-81 then head South. Avoid Baltimore and D.C. taking I-64 toward Richmond, VA and take a view of some of the Southern states, then head West. On the return you could go further north than I-40. We plotted areas of interest, left our 40' 5er at a CG using it as a hub and then took the truck to the area around the hub. Plan in advance, and I would advise having reservations ahead of time, by at least 3-4 wks. You might run into rallies and other events that might make it hard to stay in some areas. Some areas do not have cell or internet. Bring bottled water.
