I do not remember the thread, yet this subject has come up before. Anyway, for what it's worth, here's my 2 cents.
I live in Alaska; winters can be harsh and there are a lot of RV owners here. To give you a mental picture so that you may draw your own conclusions. This is what I have close to me. My house is on a large corner lot, the house behind and across the street has a large TT, two houses behind mine up the street has a cabover camper, then there is my TT, my neighbor to my left has a TT, the house directly across the street from mine has a TT as do the houses on each side of them. There are lots more within my neighborhood.
With that said, you will not find a TT, cabover camper, 5er, or MH not covered here during the winter unless it is in use. Of all the RV units within a few houses of mine, there is only one which has an actual pre-made cover (like the adco's). That is the neighbor to my left. Otherwise, the most common cover you will see throughout RV lots and neighborhoods here are the cheap blue (or silver) tarps you can purchase at Wal Mart or any hardware store. They may not be pretty, or have that custom look to them but they work (that IMHO is the most important aspect), and nobody cares what they look like when the snow flies and they are covered in whore frost and snow. Coincidentally, the neighbor next door already has a hole in his adco cover (only his second season of use). I do not say this to insinuate they are bad covers or cheap or anything. Which they are not, they work very well. Just an unfortunate turn of events.
Now, with all the cheap tarps in use out there, and the harshness of freezing (often below zero for long periods at a time) and most importantly, the occasional high winds we get (seriously, they don't hit national news much but we get a lot of wind storms with gusts in the 100 to 120 plus range). The key to being able to utilize the cheaper tarps and not have damage to your RV is to get them tied down REALLY good so they don't whip against the top and sides of your rig.
The advantage of the cheaper tarps; if you do get damage to one (a hole or rip) its easy and cheap to replace). Whereas the pre-made covers require either a really good repair job, or an expensive replacement. (example, the cheapest pre-made cover to fit my TT runs in the neighborhood of $400 and up for an all season, not including shipping. The appropriate size double lined silver tarp with reinforced grommets costs me $50 at the local SBS hardware store without shipping and is less than 5 minutes away).
Apologies for rambling, but hopefully you can get enough information out of what I am saying to feel comfortable about your decision.
Bottom line: should you cover your RV to protect it from the elements during the off season? YES!
What should you use? Whatever works best for you for your area and fits your budget.
