My suggestion is to look at actual weight stickers on TT's that you are interested in before you go too far. I found many have weights in brochure that are drastically different from what actually have sitting on the lot. This means you may have drastically different carrying capacity from originally published. Read stickers carefully, some manufacturers include propane weight and some don't.
As far as tow capacity, I would recommend you use the Gross weight, not dry weight, as you will never see the dry weight, you will always have stuff in the trailer.
