Cool project! I have been thinking of making one of those for quite some time, but I don't have a trailer frame yet. Might have to buy, and beef up a Harbor Freight trailer frame.
I like the one Eddie has. But oh boy are they ever expensive! I think for the money, I would go with a small used airstream.
I have seen some other nice little campers, but man even they are expensive! I have some ideas for the one I want to build. But for now it is just another want to do thing on the long list.
Yours looks like it will be a big one when finished. But if you have kids, I guess it will be needed!
Keep the pictures on the progress coming. The tear drop trailers, are really neat, and there is a club for them. I have seen pictures of some of the original ones, and they were really neat, with all kinds of room, and accessories! And a lot of the original ones are still on the road, giving great travel adventures. Good luck, and keep us updated.
