when discussing range, is that running the batteries all the way down or leaving an appropriate amount?

Even more important is speed and driving conditions.
EV cars excel at city driving because they can use regenerative braking. On the freeway, there is no way to recoup the aerodynamic losses and towing a brick at 70mph, aerodynamic losses are the bulk of the losses.
So how exactly are they defining "500 mile range". Even empty, it might be significantly shorter running at freeway speeds.
As far as campground charging, I don't see much of an issue off season if there are a few stray EVs kicking around. The problem comes prime time when a lot of RV park electrical systems already struggle and there are a significant number of EVs charging for all they are worth.

That pretty much nailed it. Again from personal experience. Speed absolutely affects the range. For example. We live in the interior of BC and most of our miles are on secondary mountain highways where speed limits are seldom over 90 kmh and quite often below that because of passing thru small towns. Under these conditions it is easy, and I mean EASY to achieve the EPA range rating for the car. Ow if we jump on the Coquihalla to Vancouver (similar time an American Interstate ) our expected range is closer to about 80 percent of the EPA rated range...and that is without towing a trailer. Having said that we don’t tow over 90 kmh anyway. That’s just how we roll and it’s the recommended towing speed in the province.
To your last paragraph. The charge rate is adjustable on our car from 5 amps to 48 amps. 120 or 240. So power sharing is possible. I don’t know about other EV’s. As well, the portable EVSE (charge cable) that comes with the car plugs into a 14-50 receptacle can only go to max 32 amps at 240 volts and 24 amps at 120 volts (if used on a TT30 30 amp site).
Not an expert.
Cheers.
