The ERA is an extended body Sprinter that is 24'-2" long. The LTV Free Spirit is built on the regular body that is 22'-9" long. Those are Mercedes Benz' official dimensions. I guess you can believe what you want. I am not sure why you are asking now since your mind appears to be made up.
As for "sit on a toilet while washing my hair" is concerned there are a lot of Class Bs where that isn't true at all. But then if you feel that way keep in mind you are giving up a lot of space for that belief and giving up a lot of advantages of a Class B with a slide to the point you would be much better off with a small Class C. LTV figured that out for you already and Winnebago doesn't set the world on fire with sales of the 70C compared with their other ERA Class B offerings or their small Class Cs.
