State Farm does not have a storage provision for a travel trailer or 5th wheel. The comprehensive/collision coverage is a combined coverage. You either have coverage or you don't. Your liability coverage comes from the vehicle you pull with, so is not on the rv policy to cancel when stored. There is a provision for a motorized rv. The only way to reduce the premium is to increase the deductible. The value of the rv does have an impact on the premium, so someone who owns an rv valued at $75,000 will pay more than someone who's rv is valued at $15,000.
