make some phone calls, the enforcement side don't have much of a sense of humor sometimes, first hand experience from my teen years says that a sleeping bag, coleman stove, cooler and portapotty don't make a rv
a bed with a foam matress, dorm/bar refrigerator, working microwave, sink with water supply and drain tank, toilet with holding tank, power inverter,genset and or installed wiring for the microwave and you pass the requirements.
there is a list of like 6 things and you have to have 4 of the items functioning.
if you register it as a rv you can drive it, just be prepaired for the consequences if you get stopped.
