That elevated panel thing plus all the substructure is OUT for me. Way too much weight. I won't do that. I see why they did it, but I won't do that. I'm going to have a 'typical' sort of aluminum bent bracket lifting the panels off the roof. That's it. And because they will all be linked together through the brackets, there's going to be near no real weight gain. (compared to a complete structure before panels installed)
I wish I could do something of a cool drawing like you're doing, it's great to see the illustrations! My setup is to be re-layout like as follows:
Front panel 1, as you've shown with a deflector, normal bracket height of 2 inches, centered on roof
2nd panel raised 2 inches, centered and same brackets between those panels will support both of them
3rd panel raised 2 inches again, total 4 inches higher than front panel 1, over middle roof vent opening, not centered, shifted slightly passenger side 3 inches only to make room for drivers side fridge vent top. (that also makes a perfect wire transfer tube for solar stuff, which is how my wires get down)
4th panel same upper height, centered on roof
Rear 5th panel same upper height, centered again, and will cover the offset driver side roof vent.
I don't have any skylights.. my shower has a flat roof, works great for this layout (very high ceiling actually) and we have a window in our bathroom for natural lighting.
On another completely different note, I've replaced ALL of the shocks on the RV a couple of weeks ago, and OH WOW. I should have done that when I got the thing. It rides like my van now, handles corners like a champ, ZERO top heavy swaying around, and makes my stove cover bang more (hahahaha). Really worth the upgrade. I got Monroe 555031 and 555032 for the front and rear, and although the install was horrible dirty and 4 hours, it went basically without problem, and very very very worth the time and money. I mean, they were 22 years old, and it's 10,700 lbs rolling around on them things. 'Bout time.
