Wow, nice RV you have there to ecomod! I would try to make an airdam and pannel the underside. I think that's a spot where also a lot can be won. The wheelcovers are nice and ofcourse the Kammbach
.
My major worry though, YOUR MIRRORS! You have huge blindspots without mirrors, I would say very very dangerous. Maybe some small round (concave?) mirrors can be put on just for safety? But it could also be that your camera systeam will be very good. With both a wide angle camera for the maximum viewangle and a normal camera for a more detailed view (tele).
