Hi Bob, welcome to the forum. Wow, a 10 day build. Good for you, don't let anybody talk you out of it. I do have some suggestions for you though. It would be very helpful if you were to visit other builders and users in your area. I am sure there are folks here on the board that would be more than helpful. Perhaps they'll chime in and make arraingments for a get-together. Another helpful hint, would be to do some leg-work prior to taking your 10 days off, when you plan to get started. Making a list of the perhaps hard-to-obtain materials and parts, would prevent construction delays. I think it would be a good idea to buy them and have them on hand when the time comes.
Hey, this kind of a trailer is simply a box with wheels on it, and all you have to decide, is how complicated you want to make it. Being a 3 time builder, (none of which took only 10 days), I wish you luck and be aware, we are all here to help as much as we can. Ask any questions you like, I am sure you will get very helpful advice and suggstions. Good luck on your build.
