Saying these A/C units are "designed to live outside" is no different than saying trailers are "designed to live outside", which is nonsense - they're not "designed" to live outside, they live outside because there's most often no other choice. The reality is that a properly enclosed trailer will always survive the elements far better over the long term than one that isn't, just as did any popup I owned that I stored indoors year round and which after years looked almost showroom new. The problem with A/C covers is they're generally made of vinyl and while they will protect the plastic shroud from the sun they also will trap moisture which over the long term could lead to rusting of metal parts. If longevity is the goal it's FAR better to store the rig inside or under some sort of protective shelter or at least enclose it with a purpose designed breathable cover, all of which are far better options than just leaving the rig outside unprotected because it's "designed to live outside". :R
