I have seen small motorhomes way at the back. If you walk in or take lawn chairs, take a boom box for sound
My guess is the motor home may be allowed to park in the back and then you'd have to sit in lawn chairs closer to the screen. However, the sound is radio generated from each vehicle, so it would be difficult to hear.
More than likely not but call
I've not seen a place where a motorhome could park at either screen. I recommend you call first.
