No argument that its a long ways back there from the drivers seat with even move wag, but...

It seems that +32" suspended a foot from the RV..(=44") is an exceptable extension... attach it high enough to provide the 10-degree SAE 'departure' angle. I'm just putting on a "roof" the shape of The Holy Template.  |
You'd be going down the same road as with the 'THINK FLIGHT' Subaru Imprezza experiment. He got the Subie from Cd 0.29, down below Cd 0.18.
Side gust sensitivity would be an unknown quantity, so you'd want to start out with conservative driving speeds until your confidence builds up.
Modern accelerometer sensor technology, software, and actuators would be capable of deploying aerodynamic countermeasures nearly instantly, to compensate for yaw-moments; however, that's beyond my expertise.
