I have a similar problem. Got to get the Cuda out of the wife's garage spot before it snows. All the local U-Store it places are $100-160 a month for inside storage. I lucked out and found a place in a nearby city that is an old industrial factory that they cleared out and now store boats, cars, and RV's in. Going to be $40/month which I am happy with. Going to be a 15 miles away but it is secure. If you are near Detroit I would think you have a similar place available that would be cheaper than buying a trailer. Unless of course you have other uses for the trailer, then carry on.
