I asked about it with the folks that would know, until then, I played around with numbers a bit.
14 riders per car (ride has single rider so it should be filled almost always) at, let's say, a 30 second dispatch rate. Simple math will bring that out to a theoretical capacity of 1680.
HOWEVER, let's remember that the RVs have an awkward seating position with restraints much like Flight of Passage. Many WDW guests likely will not fit and thus the ride will never run at it's full theoretical capacity. So let's say, at best it does 45 second dispatch rates - that brings capacity down to 1120. If it goes to 60 seconds or beyond, hourly capacity is below 1,000 (i've waited 10+ minutes on FoP before once on the RV...).
This could prove to be a major problem.
