Yep, Exactly what Alx said. I'd buy cheap, use it a few times (you'll know within the first three or four trips if it's something you'll continue to do) then trade up to a nicer camper if you're still interested. I wouldn't spend a shite ton of cash on a really nice one until you're sure everyone will enjoy it. I've seen lots of high dollar campers sitting in people's yards until they eventually sell them for a loss (only used once or twice).
ETA: It is definitely an investment. You'll have to have it serviced every year or two. Roof replacement is a regular thing. Not extremely costly, but you'll be spending money on it yearly. I do love mine though, wouldn't go back to not having a camper for sure.
