Prices for houses will come back down. But it may take one or two cycles/years. RVs may be at full retail. But as long as you don't buy a crazy $100k luxury camper, you'd be making a big marginal gain going to the camper.
As for renting, as mentioned rents are way up and will stay that way based on home values. So, unless you are planning to be in a two bedroom apartment for a very long time, that's probably not a good trade.
