The "Rule of 3" for RV refers to a guideline that some RV (recreational vehicle) owners follow when it comes to camping and RV travel. The rule states that:
- On average, you can go 3 weeks without any significant resupply needs.
- You can travel up to 300 miles in a day without getting too fatigued.
- You should try to stay at least 3 days in each location to really explore the area.
Of course, these are just general guidelines and every RV trip will be different. It's important to plan ahead, pack appropriately, and be prepared for any unexpected situations that may arise.
