What is the gross vehicle weight rating (GVWR) of the R Vision 23? If it's under the 6100#, you pass step one. The second step is to see what the carry capacity of your Nissan is. This is usually on the tire placard of your Nissan. It will list the weight that you can carry in the Nissan of luggage, people, the weight of the hitch itself (if not included in the original equipment), and the hitch weight of the Rvision. If the total combined weigh is less than the cargo capacity of the Nissan, you pass step two. Finally, you need to check the axle weight ratings for the vehicles to make sure you won't exceed those.
