Most B's are not going to have the storage you require, unless custom built as part RV, part cargo hauler. Typical B configurations lean toward people haulers with small kitchen and bath (like Winnebago Era 70X or Road Trek Versatile and Adventurous) or filling the whole thing with as much furnishings as possible (like Era 70M and 70A, or Winnebago's Travato and Paseo lines).
Sportsmobile does custom building for hobby and professional needs, and to get the space you would likely start with a 24-foot van.
All classes of RVs use pretty much the same RV components. The B advantage is an all-steel shell vs a built-up box, but to make the van into a house or a camper, they start cutting holes in it, and it is these openings that cause more trouble than anything else with RVs. Because of where things like waste tanks, house batteries, generators have to be put, B's often make it harder to work on the added RV stuff, but maintenance might also be no picnic on a poorly designed C.
A C in the same length as a B is going to have more room inside (because it is built wider) and should have more storage underneath. Many C's have extended frames and long overhangs (mine is almost 10 past end of frame) and this will have an impact on trailer towing. E.G. C's on Ford's E-450 chassis may high capacity for flat towing, but after the RV is finished with a rear extension, they no longer have much capacity for carrying weight on the hitch.
For towing a trailer with a C, I'd suggest something built on the DRW Sprinter platform, as Daimler does not allow extending their frames, thus the finished RV can tow what Daimler says the chassis can tow.
B's are quite variable in what they can tow. Some of the vans used to build them might tow as much as 10,000 pounds when empty, but a van filled with a house is not empty. Others are more limited to start with, but may retain their full towing capacity when the van is fully loaded.
DRW Sprinter as typically used for large B motorhomes will tow at least 4000 pounds when fully loaded. Something build on the RAM ProMaster might be limited to not much more than 2000 pounds when fully loaded. A Transit-based B what it can tow will depend on which of three engines was used.
SRW vs DRW, most C's are duallys for the carrying capacity, some small ones are not (e.g. some builds on the RAM ProMaster platform).
The largest and most capable B's are built on extended-length (22-24 foot) one-ton DRW Sprinter or Transit vans, while smaller B models are single rear wheel, and some are as short as 19 feet.
Driving on dual rear wheels with one tire flat will overload and damage or destroy the other tire, particularly with a motorhome, which is heavily loaded all the time and needs all four wheels to carry rear axle load.
