Be sure to check with your local State Inspection folks of what is legal to use on the public roads...
Once setup at the camp grounds you can use what ever you want... Lights mounted on the sides up high will usually not get you into any trouble with law enforcement folks... If they are mounted on the front or rear then you might get pulled over for it even if they are not being used... Extra lights will also fail your RV unit state inspection if they are mounted...
Speaking from my off-road JEEP days haha...
