Guess I'm real fortunate-our HOA provides a storage spot onsite in an enclosed area-your spot is yours I have a permanent structure to house the TM-part of the hoa deal- no extra cost
Depending on how much you want to spend, tarps are various prices. I bought two heavy-duty tarps for $30 apiece, and lashed them together to cover my first trailer. They lasted two years.
I then bought a single, larger (thinner) tarp from Harbor Freight, for about $25 for one. It covers my entire trailer, and I believe it will last two years, also. Better cover, as my lashed-together tarps had an opening across the top. No problem, but not a complete seal.
I have chosen to go with Harbor Freight, as I have read where others have spent $400 for a custom cover, and it lasted about 4 years. I did the math, and decided on Harbor Freight.
Thanks, LTC. I'll save that info for the next tt. Wish I'd done it on the last one!
