Welcome to the forum from us too.
Whilst my wife loves the van she won't travel with me for more than a fortnight as she misses the home and family too much.
So for longer European travel I now drive solo. I do tend to plan a general idea of the route, but don't bother with adding places to stay because there are so many. Europe is motorhome heaven.
What I'm trying to say is, when you feel ready, cross the Channel and give it a go. After a couple of days you'll feel completely at home and thoroughly enjoy the drive.
