I did my first tours from hotel to hotel/ B&B and got back into camping after a 25+ year gap because I wanted to go further for less money.

Now, I think I love the camping as much as being on the bike!

I can't offer any advice on where you can camp, but my usual routine would be different if I'm in a campsite or wild camping.
Campsite routine is to set up camp, do chores - laundry, bike and cook dinner. Then relax.
If I'm wild camping I'll try to eat before I pitch my tent and pitch my tent as darkness is falling. Then it's read & sleep.... or just sleep.

If being bored is a genuine worry, then seriously consider a kindle! A great bit if electronics to have. Books, magazines, whatever you want to have on it. For longer tours I'll send important info & maps to it as a document/PDF file - great to have as a backup. But I can't recall ever being bored!

The one advantage of a tent strapped to your bike is that you have almost total freedom to go where you want when you want.
Happy Trails!
