Teardrops n Tiny Travel Trailers

09/26/2020 The top is raised 12 inches in this shot, supported by sticks in each of corner, and I left the jack and support to illustrate the lifting mechanism. It's a 2 stage lift to raise the top 34 inches, so to get there, I would raise it another 5 inches, insert 17 inch PVC supports, and a shorter sonotube (8 inch dia. cardboard tube for pier construction), between the jack and the tall sonotube support, then lift up to 34 inches, and switch out to 34 inch PVCs. I had expected to install a round, laminated (table-top) support, centrally in the ceiling, but the extra weight of one layer of 1/2 inch plywood, in both doors, (for security), moved the center lift point back 8 3/4 inches, to under the insulated skylight! I already had a thinner, 12 x 36 inch, laminated board I installed as a removable table/desk across the back door, so I now use it as my support board, to bridge the skylight. After the lift, the floor area is cleared by stowing the jack and sonotubes away. The top, once raised, is supported by a bolt in each corner, and 2 straps over the roof, down to D Loops at the frame. The straps are also used for travel mode.
