Our Itasca Class C has about a 5 inch step-down into the cab and a flat coach floor from there on back. Hence, it's somewhat of a basement design.
What this gets us is five (5) exterior storage bays with plenty of height for items and two (2) exterior storage bays going laterally across the coach tucked between the frame and the coach floor for storage of long items. These seven (7) storage bays, because of the basement design, give us enough room to keep the Class C fully loaded the same for every trip so we're ready for anything, anytime, on any type of trip. This makes packing the RV easy because food and clothing are the only considerations, as everything else is always in the RV.
We don't care much about looking out the front cab window when parked, but of course we somewhat still can. Our coach is 101.5 inches wide, with 6'8" of headroom. It does not have a slide, and with only the two of us it's widebody design takes away the need for a slide. What no slide gets us is a lighter overall RV weight, a stronger coach box due to better wall shear strength, and more leak proofness over time.
