Any business is going to show its product in the best possible light, even to the point of being a bit deceptive.
Look at RV websites. How many use wide angle, even fisheye lenses for their photographs. Looked at one only yesterday & not only were these type of lenses used but the placement of furniture was such that it gave the impression that there was more room than actually existed.
CGs are the same way. The best sites from the best view angles will be used for promotion. RVParkReviews.com is hands down the best info source. Ignore the most glowing review, ignore the most critical review & pay attention to the rest.
