I got a tent shape naturally by following the contour of the roof with my brackets. The tent shape dramatically increases the rigidity of the structure. It’s not obvious from my other pictures but I have a 14” cat walk on the driver’s side of the panels. This is convenient for sweeping off the slide outs and cleaning the panels. It’s also worth mentioning that this trailer is high off the ground and I put the tallest tires that I could on it so the frame is a full 2 feet off the ground. This might make a difference for wind resistance. One must also consider that since it is towed how the wind hits the trailer will be affected by the dynamics of the tow vehicle. I can’t get a straight on side view of the camper right now as we are parked in the trees and I can’t get a unobstructed view straight on.. from were the airfoil attaches to the front panels to the back of the trailer is 32.5 feet. There is a space where 2 panels are missing immediately after the first 2 panels because of the roof ac. My thought is to remove the roof ac and install a mini split and 2 more panels in that gap. While I am dreaming my ideal setup would be 12 of these https://a1solarstore.com/solaria-400w-solar-panel-mc-4-powerxt-400r-pm.html?msclkid=a7a6002f77611db1196562ace98e30f3&utm_source=bing&utm_medium=cpc&utm_campaign=First bing feed&utm_term=4586612758817463&utm_content=BingAdGroup that would cover the entire roof and give me 4800 watts up there.very impressive install. pretty nice integration, I like the tent shape of the panels. You should share that somewhere in Show and Tell.
you could try posting a picture directly from the side like perfectly parallel to the RV. Some of the Simulation Wizards here could create a black and gray model and run it through the fluid dynamic flow simulation and try various tweaks.
