I've been lurking for awhile, and decided it's time to join in and post. We're a husband, wife, and two year old daughter.
We don't have a trailer yet, but are not newbies to camping at all. I owned a EuroVan Camper for ten years, and had a lot of tent camping and backpacking experience before that. Wife is from Venezuela, and she did a lot of tent camping, mostly on bus trips, before coming to the US. We sold the camper van last year, bought a boring but practical Honda Odyssey minivan, and we used it for a three week tent camping trip a few months ago.
With a toddler in the house, we don't have time, space, or tools to build our own. We're definitely looking at the "buy, and do a little bit of customizing" route. I'm handy with electrical and small carpentry projects, but I wouldn't want to build a full galley. Customization is likely to be more along the lines of installation of fans, lights, flashlight brackets just inside the doors, small shelf to hold eyeglasses while we sleep, etc.
While I can appreciate the retro appeal, it's not why we're thinking teardrop. We're really just interested in a practical and lightweight comfortable camping experience.
We'll probably want a bunk to allow the toddler to sleep crossways in the trailer until she's old enough to want her own tent.
We visited a dealer that had a Little Guy Rascal and 6 wide sport trailer. I wasn't impressed with the galley or lack thereof. On our last vacation, we stopped in at So-Cal Teardrops factory in Ontario, CA. I was very impressed with the build quality there, and the folks were very friendly.
