There is reciprocity in Driver licensing in all 50 states and Canada. This means whatever licensing rules apply to you in your home state will apply in all 50 states,territories, and Canada.
There are additional FEDERAL licensing requirements for operators of commercial vehicles over 26,001 pounds or over 16 passengers. These are also reciprocal. Correctly registered vehicles are also reciprocal.
There are some "grey" areas such as a class "A" CDL where a truck towing a trailer over 10,000 pounds and the combination is over 26,001 pounds. (Dually pickup and a stock trailer for instance.) Also there may be special livestock restrictions that are unique to states. This happens a lot across state lines. The operator may be exempt from a CDL if it is local agricultural, or owner hauling his own products locally.
No RV restrictions can be imposed by another state if not required by your home state.
Hope this helps. BTW over 41 years experience in this field.
