I carry my 18 Outrage on a galvanized channel frame trailer, carrying capacity of 2800lb, same tires, after having an EZLoader built as you describe with 3 x 3 frames, fail on me.My trailer is 80" width overall, so that is not an issue. The boat will sit over the top of the fenders. It is the 3" x 3" frame members that concerns me, especially the tongue & side members. Whether the frame be of tubular or mill channel sections, the 3" depth (height) dimension is marginal. For tubular trailers, the side frames should be 3 x 4. 3 x 3 cross members are OK.
On my trailer, the tongue is 3 x 4, and main frames are 4" channel sections. The cross members are 3" channel sections. It is one solid trailer, built like a tank.
I prefer channel section frames, first all connections welded, then hot dipped. Tubular trailers that are bolted together will flex, squeak and rust out at these connections, as will the bolts/nuts. Tubular frames can look great on the outside, but rust through from the inside, where you can't see it. That is what happened on my EZ Loader, although it was not galvanized. Never buy a painted trailer, especially if it is tubular, even for freshwater use.
