class C with motor cycle storage

Small motorcycle can go on a rack. Large one not so. Plus if it's a 30 footer you don't have the cc.
A 25 or 26 E450 will give you the cc you need.

Is there such a thing in class C?

I "converted" my C to a toy hauler by adding a small trailer.

There are some new considerations to learn with a trailer but it has worked good for me.

The Thor Outlaw is one.

What you're looking for is a "toy hauler," an RV with a sort of garage area in the back. Thor makes a class C toy hauler (the Outlaw). I don't think they have any drop-down bunks in the back, though there are some folding sofa/bed units available.
