Got to tell you that if you want an apartment on wheels (as I call anything like a 94" and bigger sleeper), then it may be hard to find. I drive another C unit every once and a while to cover a load for a customer. It has a 18 foot box and another small box on it for equipment. It is 40 feet long and it is almost the same as driving mine which is 31 feet and 6 inches. The only thing I have an issue with it is pulling into Walmart, I can't park it like mine but have to go across the parking spots - other than that, it is the same thing.
IF driving is an issue, think about getting a rear view or blind spot camera. Believe when I had mine on the truck, it was so easy to make lane changes and backing it into tight dock spaces.
