Yes, hire someone to build a pole barn/ shed for the rig. I don't like covers, they tend to induce ventilation (obvious) issues and condensation is a problem where we live. If you are in a desert environment (extreme low humidity), maybe it would be OK but I'd get a pole barn/shed and park it under cover. It is true that being under a shed cover will extend life of sealants somewhat, even help overall appearance over time.
