Gap between roof and front cap
When I first bought my motorhome (12 years ago) I noticed a lot of caulking on the left side of the seal between the one piece fiberglass roof and the front cap. It was obviously that there was a gap...

With 3/4" OSB sub roof I would just screw it down with 8 x 1" screws. I would even go a step further and add a fat bead or RVT between the cap and the roof. Screw it down clean off and excess RVT the cover everything with EternaBond. RVT isn't what you want to normally use but in this case it will help hold the two surfaces together.
I would not try and bolt everything down with heavy hardware into the sub structure metal framing. A coach needs to flex ever so slightly when going down the road. Make everything as stiff as possible and something is going to crack. You also need to consider thermal expansion and contraction.
