I just looked up the laws in my state of Oklahoma and they state:
Section 1-152.1 - Recreational Vehicle.
For the sole purpose of the classification of vehicles as provided in Sections 1-107.1 through 1-107.4 of this title, a recreational vehicle shall be deemed to be a Class D motor vehicle, provided such vehicle is a self-propelled or towed vehicle that is equipped to serve as temporary living quarters for recreational, camping or travel purposes and is used solely as a family or personal conveyance.
Section 1-107.4 - Class D Motor Vehicle
1. Regardless of weight:
a. is marked and used as an authorized emergency vehicle, as defined in Section 1-103 of this title, or
b. is designed and used solely as a recreational vehicle;
I bold ed above to point out in our state that the weight does not matter if its an RV as defined as above. I only need a Class D licence.
Now my return question is, if I drive into another state am I held to my states licence requirements or theirs?
