I don't know if anyone mentioned that the 40' has a wheelbase of 276 (if the brochure for the tour is correct) and the 42' has 279. While talking to a couple of Cummins-Onan guys, I was told the generator door was hinged at the bottom and swung down from the top, no two piece opening, no slide. Straight axle, no slide generator, no side radiator, 400 hp, no pushbutton entry and higher prices I just appreciate my 08 Vectra TD more. The 40' tour is $300,000 and the 42 Ellipse is $330,000. The 40' is 40' 7" in length and 42' is 42' 10". Fuel tank is 150 gal. for the 42'. Trailer hitch on the 42' is 15000 lb. drawbar and vertical tongue weight 1500 lb (42 AD). 40' is still 10,000 and 500 lb.There are 3 new coffee glazed wood stains which look pretty good. The Sunsplash yellow body paint I'm not sure I want to see. The bed folds to get the 2 opposing slides in. I would like to see the 42' with the slides in, I guess I could go on a test drive to see that. Some observations.
