Any thoughts on putting the motor behind the cab?
I saw a 53-56 Ford cab over put on a IH bus chassis. They moved the motor to the middle, right behind the cab and put a sleeper over it. They used the IH diesel bus motor, probably shorter than the Cummins, but even at that they didn’t put a floor in the sleeper. You can still access most of it by getting under the side between frame and sleeper. He has a 20-24’ duck tailed flat bed on it.
Been sitting several years now, the old guy never drives it but won’t sell it, either. I tried to buy it last time I saw him out in it, no luck.
