For a whole family? An RV is cramped. Moving around is difficult and a basically one-at-a-time deal, weather trapping everyone inside is miserable, and basically the only time you get to stretch is when you're parked and everyone can get out. You really have to move around inside one to get a feel for how tight the space is. Go to an RV dealership to check one out, and then think about what it would be like to have two or three or four people living in that space, almost all of the time.
Do some writing exercises with a family getting irritated with each other over the close quarters, and I think you'll have a good start for your story. I wouldn't worry about the "vampire" stuff too much; there's a tendency to over-worldbuild. "Family travels long distances in an RV" is more than enough material for a hundred stories, so you don't have to overcomplicate from there.
Mm-hmm. I know, and that's what frustrates me. The opportunities for me to walk around inside an RV are basically nil. For a good while right now, anyway. I do take your point, though, that that experience is necessary to write it accurately. I have spent some time in R Vs
...just not in several years. When an opportunity arises, though, I'll be sure to take advantage of it.
I've been thinking about that some, and I think you're right. I'll do that - I don't need the supernatural stuff. For now, I think I should just focus on the people and their immediate situation, and put the supernatural stuff to the side. I do
tend to over-worldbuild, so...yeah.
