I think some new to camping folks may get discouraged at the lack of sites and dates available and the cost to camp in the first place
Really depends...problem is too many "new" RV'ers don't think outside the box so far as where to camp. They absolutely must be in a campground, and they absolutely must have power, and some refuse to even go anywhere without water and sewer hookups. The thought of camping somewhere where they have to rely on just what they bring (even if they're in some gigantic luxury unit with huge tanks and batteries) doesn't occur to them.
Buying isn't for everyone if you do the math on how much you pay per outing. If you're like we used to be when we camped 200+ nights a year it's easier to swallow. If you're like a lot of new RV'ers who go out 5 or 6 weekends a year, well, the numbers are scary.
Most people never see beyond the "only $299/month" figure though. For 30 years.
On the "where to camp" thing I've been looking at harvesthosts.com - looks interesting. Not a ton around here however but given a regular campground is $50/night right now it only takes a few nights to break even then I guess.
