Any E-Series owner will likely say legroom is “broke”, or at least can be made better.
My understanding is that Ford will continue to offer the 6.2L V8 which is wider than new 7.3L V8, so they may not be able to change doghouse anyway. I haven’t seen a single motorhome yet with 6.2L V8 (all had V10), but seen quite a few commercial vans listed with 6.2L.
It will be interesting to see difference in cost and fuel economy between these two engines.
