I have a fairly strong hardtop (FRP/foam over 1" thick) that I intend to mount 2 panels
on; however, it does still flex measurably when folks walk on it.
Has anyone considered mounting the panels
at only 3 points to insure they cannot be twisted or stressed by the distortion of the deck
? Alternatively, I could build a stiff subframe. I suspect all of this is unnecessary since the flexing is perhaps 1/8" over 4', but I thought I would ask.
