The trailmanor is an interesting concept. Very long with composite construction on a single axel fram. Any idea how they do that? I am thinking about a foamie to be designed like the old HiLo but in foam.
Any thoughts on the frame for this? Thinking 7 x 16.

Links to what you are referencing would be helpful. I'm pretty sure this is the company you are thinking of: http://www.trailmanor.com/WebDocs/Showr ... truct.html
Not much more than laminated floor design. What style of floor design? How they do they make it? Who knows what method they choose. There are many to chose from.
OK,
That's it.
A possible laminated sandwich construction made with I-beams for the main rails, and C channels for the tongue. The main rails are parallel and at the width needed for attaching the axle. At the axle they would need to be plated for some additional thickness to retain their strength when the flange is drilled through for the bolts, or if they are aluminum, a steel sub frame is used to distribute the load over a greater length of the I-beams. The cross floor joists are made with 1/4" softwood and 1/2" hardwood. 1/2" is used where stuff will be attached to the floor, be accurate. Cross joists will be carved to tightly fit into the sides of the I-beams, and have top and bottom surfaces in the same planes as the I-beams. The reason the cross floor joists need to be notched to fit tightly into the sides of the I-beams is to distribute vertical load from the floor to the I-beams. I'm not sure of the spacing for the cross joists as that depends on the surface properties, mainly it's stiffness. The spaces between the cross floor joists will be filled with foam. The foam partially supports the floor skin, but it also supplies side pressure to keep the cross floor joists from buckling. The bottom surface should be able to be FRP or aluminum skin while the top surface would likely be a single sheet of FRP or plywood with a finished wood laminate or linoleum floor glued to the top of it. The whole construction would be glued together and vacuum bagged to make sure it glued up properly. Note, the I-beams could also be placed fully under the floor. In that case the cross floor joists would be continuous from side to side. Also C-channels or box beams could then be used. Note, placing the I-beams inside the floor structure allows them to gain stiffness and strength from the structure of the floor. In the spot where the wheels are, obviously the floor would be cut away for them. There would likely be a border frame of metal or wood. Some engineering analysis would need to be done to see if the floor design would work. An area concern are the areas to the outside sides of the I-beams. I figure between the I-beams there would be no issues if the outsides are strong enough to work.
Our 3" floors feature a special laminated construction that is stronger, more durable, lighter, and better insulated than other trailer floors made from particle board or plywood. That helps keep the weight of the whole trailer low for easy towing, yet gives you a floor you can count on. And our insulation means you stay more comfortable year-round, and use less energy to do it.
