There are plenty of Tear Drop vans if you go looking on the internet. Jayco make the J-pod - basic but can be dressed up, there are a couple of other manufacturers as well. Prices start around $23,000. But there is some satisfaction in building your own - I built my camper trailer from a "kit". Bought the trailer + tent, modified it all to our use.
