It's common for new FTers to run around the country a couple of times... lots of miles and then settle down and do areas of the country in more detail and fewer miles. Try and pick a section of the country on a three month basis. The longer you stay in one place the less planning it takes.
We will do three month out West with only a general idea of the areas we want to visit... usually boondocking during the week and traveling and resupplying on the weekends. If you show up at a USFS CG on Friday with a big rig and no reservations you are in trouble but show up Sunday afternoon or Monday... no problem.
You will be surprised how easy it is to boondock with a big rig. With plenty of water, plenty of power, and a little planning it's lets you stay longer if you want because you do not have reservations. Now in the winter with fewer CGs to choose from you need some planing. This is the best time for those doctor visits/appointments.
Do a search on "" on here as that will solve the mail thing.
