You might consider PassportAmerica or Happy Campers and look in their books for the half price campgrounds. I have made my money back several times over with PA. You can get some ideas about where you might want to stop. Being retired military I also look for FamCamps along my route. I wouldn't worry too much about setup and takedown. It's not all that much trouble, and it looks like you have plenty of help to boot.

I took three long trips last year (solo), often setting up and taking down every day, a couple times staying in one spot for three or four days where there were interesting things to see and do. I'd say take the TM, enjoy your vacation, and if you can, keep a day or two open for serendipitious finds along the way.
