When your RV sits in storage for an extended period of time many unexpected things can occur. Batteries that were fully charged when you parked the RV are now discharged, tires that were properly inflated are now under-inflated, seams and sealants crack and separate from the surface, and insects and rodents build nests in and around the RV.
There are other concerns too, that can come from where the RV was stored, and how it was prepared for storage. If the RV was stored outside, exposed to the elements, the exterior and roof can suffer the brunt of Mother Nature’s harsh winter conditions. And, if you did not properly winterize the RV water system, there could be damage to the plumbing.
