What late model makes are 96" wide & <40 foot long?

I don't know of any late model US built diesel Class A that doesn't exceed your width requirements with the exception of the Tiffin Allegro Breeze 32BR and the Winnebago Via (which is even smaller). There have been Breezes converted to RHD. You might want to contact Tiffin Motorhomes with your specific requirements.
