If there door was already open then you are liable for the damage. It does not matter if it is on private property.
any vehicle leaving private property and entering a public road ,is at fault. all vehicles leaving private property MUST yield to vehicles on a public road
Based on your description the car that backed into the other car should pay for the damages. You can't get a ticket for backing into someone's car unless they were either drunk or had no license, both instances in which police should be summoned.
If it is business property like gardening equipment, you can cover it under personal property which is separate from your auto coverage. If you rent and have personal property coverage, they should have a limit for the business property on that policy. If it is stuff you sell it would still be business property and they usually cover about $2,500 worth both on and off premises. Check with an insurance agent for a quote.
Of course the party that is deemed 'at fault' will owe for the damages to the innocent party, or perhaps some comparative on each. The insurance companys will sort this all out in their investigation. Too many things go into this that you were unable to provide, (ie where is the damage on each vehicle, who had 'control' of the ''road'' etc)...
This has alot to do with if the impact is on private property and if you had permission to park in the friends driveway, then ultimately if you want to remain friends. If it's an easement or such, the other answers may apply.Another View: Whether you are on someone else's private property makes no difference, the striking vehicle is at fault. Your insurance companies will have to battle it out.
You need to have your RV included in your insurance policy.
