Nothing wrong with triangular beams. We will be using them on the Elementarry's with carbon rods in the corners and foam webs. The main reason for using them is lightness and deflection of water downwards. They will also be telescopic for trailering.

I think the basic concept with the triangular beam is to come up with
an I-joist type truss that will carry the major loads in the vertical
plane, then box it out with skins so it looks better, is more aero,
and of course picks up loads of strength when the loads aren't
vertical.Therefore adding weight as you add to the I beamSo why not just go for the triangle in the first place?Is it because of the fore and aft loads?Or is it because of torsional distortion?RgsTony
