The cabover makes for great storage. That's why we intentionally bought one with the bunk up there and removed the mattress. The difference in fuel economy is minimal.
Same for us removed the mattress and use the cabover for storage of light bulky things. As far as walk around queen beds in small motorhomes its always a trade off. They seem to take up 2/3 of the space and leave you with a wet bath and super small kitchen. Also we wanted nothing behind the drivers and passengers seats that would stop them from moving full back so we can recline them full back. They make nice recliners. Many rigs have some thing behind the seats and you can not even move the seat back or tilt the back any. Found one I could not fit between the steering wheel and seat. I am 5'8" and 170 lbs.
What ever you do, set it up for travel and then spend a couple hours in the drivers and passengers seat and be sure you find the comfort you need. Lots better to do that and end up with some thing you can put in long days traveling than find after a couple hours you are in pain.
