1. Drop the "disappearing deductible"!
2. Drop the roadside assistance and get Coach-Net.
3. Drop per peril (100/300/50) and get $500,000 combined. That $50,000 property damage liability is way too low. Your at fault and total a motor vehicle and many are worth more than $50,000.
4. Add uninsured motorists property damage.
5. Drop medical payments. Your liability insurance will pay any medical payments for an at fault incident, just like medical payments. It is double insuring.
6. After confirming your homeowner's insurance will cover your liability at the campsite (most will), drop vacation liability. If it doesn't, raise vacation liability to at least $250,000.
