TexAxis, unless it becomes a new floorplan, I don't see how they could make the bathroom in 24.1 larger. I personally wouldn't spend anything near $15k for a larger bathroom anyway. MHSRV has all the same floorplan numbers listed for 2018, so I don't expect change in that area.
Jamie, that could just be a typo or oversight since it appears it's information that MHSRV would enter into their website. From what I was told the E-350 for 24.1 floorplan was a temporary revision. I wouldn't have an issue with E-350, particularly if they included the new V8.
The sketch I posted above, if drawn accurately, suggest there "may" be some major changes around the cab and front cap area. Actual pictures should soon tell if they are dealing with E-Series chassis being much narrower in front in a different manner. The sketch shows front cab window is now mounted within the side wall instead of adjoining the top of front cap on previous design.
Originally, Thor listed the Axis/Vegas as 7'-10" wide in back, and 7'-3" wide in front. It's not clear on sketch if they are changing the width transition. Aesthetically, that could make a big difference. The only other Class A built on E-Series looked a little goofy because it wasn't narrower in front like the Axis/Vegas.
