I have a 2018 337 RLS; does anyone know how far apart the roof trusses are? I hope I'm wrong but they appear to be 48 inches apart. Thanks in advance. Edit: After doing a bit more research, its my understanding the trusses are 16" OC and that every 48' is the plywood seams. There just seams to be noticeably more deflection between the plywood seams especially if there is suppose to be a truss ever 16".

The roofing material is 3/8" plywood so you may be getting a little flex when you step between the trusses. GDRV doesn't want to use any thicker roofing in order to keep weight down and to allow for bending the plywood to the arc of the trusses.

Hi Rick,
Not meaning to jump on your discussion with Jim, but we are not allowed to share drawings. If you contact Grand Design Customer Service with your VIN, they will likely provide you with whatever drawings they have that you might want . . . with the same caveat, that you not share these on any public forum.

Hey Rob. No problem jumping in...the more the merrier. I figured as much that sharing of drawings was not allowed, but I had to ask. I'll email Grand Design Customer Service and see what they can provide. Thanks again.
