another Bev RV

Any time you see a mileage figure on an electric vehicle see if they give you any average speed figures to accomplish that mileage. You might be surprised that most electric vehicle mileage range figures are driven at 28 to 32 MPH flat and level. If you drive it at 65 MPH the mileage range is cut in half or more.

Very true. For a city bus, regenerative braking can really have a big positive impact on range and since it never gets above 40-45mph, wind resistance isn't a big issue.

For compact BEV cars, a ton of effort is put into aerodynamics along with a massive battery bank relative to the overall size of the car.

Your average brick shaped RV has horrible aerodynamics. You are looking at 40-50kw continuous output to maintain freeway speeds. With 108kw battery bank, that's more like 130-150miles at 60-70mph.
