Not easy to photograph this thing , but it kind of looks like a trailer now, still a lot of work left, I need to fill in the seams next, had to make some changes, and removed the I-Beams from the front axle forward, previous trailers , the way I mounted the sides had the bottom of the sides more below the frame/floor piece, I pretty much kept the bottom of the sides level on this one, so with the I-Beams, they got in the way of the some things, but I will still use for the axles and help in mounting them.
Evergreen strips #109, .010x.250 was used on the sides where the sides are attached to the frame.
And what I did to help get that curved shape on top of the gen compartment, sized up the PDF and printed it out and used that as template to cut the plastic, I wish I would of that of that before the first too attempts
Look at the storage compartments between the spread axles.
