It’s interesting that it appears they are using wood roof trusses now. Our rig used stamped steel trusses. In 2014, at the fall rally, we went on the factory tour, and they were using molded plastic trusses. If you are using steel struts on the roof, I would be concerned about the metal wearing into the roof material more than I would worry not hitting trusses when attaching the struts to the roof. Also, not being able to physically see each screw location under the struts to verify that the Dicor caulking was intact could cause roof damage from leaks. I’ve not seen any solar panels laying in the roads that may have flown off of RV’s traveling down the road, so however most are attaching their panels seems to work. However you ultimately attach your panels, I’m thinking the plywood roof material is strong enough to walk on, and will be plenty strong enough to secure the panels without worrying about hitting the trusses.
