Welcome, Jay, and congratulations on your Raven-with-Rohloff. Matt will be your guy on the care and feeding of a Raven Tour, and a number of us have the "new" Raven.
I've had mine since the spring of 2014, and it's been an excellent bike, comfortable and reliable. It excels as a touring bike, and I use mine mainly for that. (I have a city bike for errands, and I don't like to leave my Raven locked up and out of sight. And, I have a light touring derailleur bike, slightly faster than the Raven, which I use for day rides.)
A followup to Martin's comments about lower gearing to ease the stress on your knees, spinning more gently but more rapidly in hilly country: When I first bought my Raven, I used a 17T sprocket at the rear, with a 38T chainring at the front. That was OK, but after a year I lowered the gearing about 5% by switching to a 36T ring at the front. (Switching chain rings on the Raven is dead simple.) I found the new setup much easier on hills above 8%. More generally, I spent more time in the upper register of the Rohloff, gears 8 - 14. I live in a hilly part of Ontario, but was born in Dorset & have spent time in Devon, so I know that you'll be dealing with grades in double digits.
I've been privileged and lucky not to have any knee problems, but I have a lot of mileage on my body--I turn 73 in three weeks--and I've found that Lower Gearing Enhances A Feeling Of Well-being.
Other riders use higher gearing than I do, but I've found that the 17 x 36 works very well for me.
Good luck exploring your bike and the countryside!
PS: i've heard tell that it rains in Devon, so you might want to look into getting a Hebie Chainglider to cover and protect your chain. 'glider devotees are a little cult within the church of Rohloff, and there's several of us here on the Forum who can tell you about the myths and the various chants and incantations.
