Sub floor finished

Last weekend I completed my foundation for my house. I framed up the floor structure with screws 24 inches on center. I built it in three sections to make room for the wheels. I found some sheet metal on craigslist for a dollar a sheet. I covered the bottom side of the frame with it to prevent penetration from road debris. Before I installed the sheet metal I cover the bottom of the frame with a 3.5 mil plastic sheeting as a moisture barrier. I sealed every joint with silicone caulking and screwed the joints every six inches then tape the joint with metal duct tape. I then bolted the three individual sections together and sealed the seams. I then insulated the gaps with fiberglass insulation and coverered that up with 3/4 inch osb, which I attached with liquid nail and three inch screws. It is now ready to be placed on the frame which I got welded on tuesday by a friend. Saturday is the day to move and hopefully the weather holds. I still have to take the trailer to the car wash then apply a coat of anit rust paint. If I get that done early saturday I should be able to start framing later that day. I will post pictures as soon I have time. So far I have estimated that I have spent not including the trailer, around $300. So far so good
