It's a big investment, one you'll use often once you find it ... I drove 1300 miles to buy one in 2002, sold it in 2008 and upgraded ... we still cross-country camp in the 2008. The 2008 we bought was new, at auction, and 800 miles, which makes a difference, of course. But we had been looking for quite a while, both new and used.
It depends on how much a hurry you are ... eventually only you can decide if it suits you and how much to spend. You will find one you like and in your budget as long as it's a reasonable budget and camper is in acceptable condition.
Might take awhile, might not. Personally, we'd drive that far again for the right camper at the right price. Hope that helps. Good luck ... B & G ...
