I don't know how practical that side loader would be. Running the bike in and out once parked would be a probllem unlike having a rear loader at a pull through site. Of course, that is living space. Even if you waited to load after you pulled out of the site you could have a problem getting a straight shot into the back.
In any case, a rear ramp with a garage seems to be the best configuration.
