Midcars, Southcars and Ecars nets all come to mind. 40m is a very active band during the daylight hours and there is lots of activity from 7.125 to 7.300 if you have a rig and antenna that will allow you to operate. The three nets are mobile radio oriented and would be a good starting point for working 40m.
If you are traveling at night 40m will give you some coast to coast coverage and some DX. Line of sight to 300 miles depending on band conditions during the day. Perfect to keep you company while on the road. Ham sticks are cheap too....so getting on 40m is no problem.
Google is you friend, so look up the three nets I mentioned.
I've worked 45+ states + Canada multiple times during daylight hours in the last 2 ILL QSO party. The first year was close and far at the same time. Never heard 40 open like that before. I was operating portable both times with a dipole at 12-15 feet.
