Narrower Class C with cabover bunk on Chevy/Ford E chassis?

Every length (21'-31'), and every model (9 to choose from) Phoenix Cruiser measures the same slim 93" wide. It is very hard to find anything narrow these days built on a capable E-series chassis. Years ago slim rigs were easier to find, and with cab-over bunks.

I am not a fan of the Sprinter or Transit. But that is me, just me. People who own them love them, and I am happy for them. I got a list of reasons why I prefer an E350/E450 or a GM 3500/4500. But that is another topic.
