Dan, I have no personal experience of MDC, but a few members have them and I can't recall anyone being unhappy. I think all have been realistic about what they bought. It's probably not going to do multiple trips to the Cape, but we buy what we can afford.
Don't discount the 2nd hand market, there are some absolute bargains out there. You'll still spend $5K, but possibly get a camper that has better canvas and maybe fitted out with battery and kitchen etc.
