Teardrops n Tiny Travel Trailers

I'm hoping to pick up a harbor freight trailer next Friday (It's on sale). I have two questions, well actually have have hundreds of questions, and some that I have even thought of yet, but first two are I want to keep this an inexpensive and light as possible using the generic benroy plans that mike has posted. Any idea of a ballpark as to the cost of the one Mike built and about what it weighs. I'll probably pull it being a toyota corolla. (They say not to pull it behind a scion.)

I have not price materials lately, so I'll have to let someone else chip in!

Mike...

Thanks Mike for your response. Actually, I've been trying to locate the spreadsheet that someone developed awhile ago. Would it be possible to get a copy of that? If so, I could work out the expenses. Also, Do you recommend a regular lumber company or is it okay to go with Home Depot? What are your thoughts on the Harbor Freight trailer?

Thanks
