Stunning Replaceable Cab Class C
My first motorhome was a 72 Winnebago Brave I drove new off the lot. In the last mere half century I've seen a lot of different motorhome designs but this one that I just came across by chance totally floored me:
Coxx Mobile Systems | X-Low chassis
It's not listed specifically as a motorhome but not only would it make an awesome extra low overall height unit (imagine the reduction in aerodynamic drag), but the concept of just unbolting the entire cab and replacing it while leaving the rest of the unit untouched has officially blown my mind.
I searched for Coxx on this forum and didn't find anything. Has this been discussed before?

Very interesting, I see they do go to 4 meters (13 feet) in height.
But, you could build a very nice rig under 8' with that chassis. Along with the small class A styling using the short cab. 25' with a low overall height and full air ride would be sweet.

I think it opens up all sorts of possibilities. If you wanted to go totally nuts you could do a full two storey that didn't need to be expanded upwards at all. Figure around 7 feet for the main living area and then about 4 feet for a second storey sleeping only and/or kid's play area and/or storage area. But even if you wanted to stick to a more or less conventional format that low overall height could allow for the whole height of the living area to tuck behind the cab without any significant upper protrusions. Let's not even mention the wheelchair accessibility of such a low floor.
Then when you've toured around in it a few years and worn out the mechanicals you just buy a new cab and you're on the road again. Heck, by then you might be able to swap it out for an electric cab.
This is one of the things that I'm myself for not thinking of 20 years ago!

Interesting concept .
For a Motorhome conversion , a major downside to the design are the main frame members.
The section appears to be small and lightweight which will impact towing ability and GVWC ..
I'm sure the issue can be mitigated through engineering changes . However , it would probably raise the deck height significantly and add to the vehicles dry weight .
Great idea for it's proposed uses , for a RV conversion we'll have to wait and see.

My laptop won't open the link or most links to that company. One site I could go on said they're making vehicles with up to a 16,500 # GVWR, which is 2,000# more than the Ford E 450. I have no idea what the GCWR is.

That's very similar to the old GMC MH's with the toronado front drive. I forget just what they were called, but they were very low and aerodynamic. Still lots out there, and more just sitting and slowly sinking into the ground.

To the OP - EU chassis, EU certification. Cost to bring it to the US, certify it, and build on it - way beyond any company's willingness to invest.

Somewhat reminds me of what Winnebago did with the Rialta. They obtained the front end of the Euro vans (they actually came shipped back to back with splices in between to hold them together) and then mated their own rear chassis and axle to it.
The LeSharo was done in a similar fashion using a Renault delivery van cab/front frame/drive train. (what a piece of junk that was)

Being that low to the ground and in a decent length, would that present challenges with some raised RR crossings, etc?

Yeah ... that was my observation also. The frame looks too low to the ground for me.
We want our MH to be flexible enough to take on dirt/gravel roads whenever needed with maybe even some ups, downs, and moderate ruts on the road surface - so some semblance of ground clearance is necessary. Our Ford E450 based short Class C gives us that.

Never work. IMHO
With the frame so low, how would you run the grey and black tank lines or the black tanks itself. You would need to add a sub floor above the frame and below the floor to house everything that is usually below the frame.
I have the 28Z model and even that has the 3" black tank line runs across and below the driveshaft

From what I understand from the site, there are two heights available, the 250mm and 400mm. I'm not advocating for this chassis to become a motorhome (I just thought the "unbolt the cab" thing was genius) but it would be fairly easy to develop a floorplan with all the water-associated features in one section of the layout with a slight stepup. Where there's a will there's a way!
