With anything ordered at this time, unless it's an "in stock" item, you will have to figure in for COVID-related supply chain issues. Even IF in stock, having a qualified crew to assemble might still be an issue.
That said, an RV port, IMO, is the next best thing to fully enclosed/climate controlled inside storage. We built one in 2010 (https://www.irv2.com/photopost/showg...GzNAnujcnBszQw
) & it was the BEST thing for keeping our RV's protected from sun/elements. Plus it was SO nice to stay dry when hooking up in the rain.
