I would imagine any manufacturer or Good Sam would be able to closely identify the approximate number of RV's on the road since those metrics are valuable for marketing and sales. You'd have to reach someone up the ladder for that kind of data. Marcus perhaps can chime in. In the "for what it's worth" category, I wouldn't think you'd need to concentrate your target market on just A B and C motorhomes. TT's could be a market too. If I understand the product correctly, a generator will suffice to run the device.
