You are right, it would be cheaper to have the open trailer. But I know I had lots of little stuff go missing off open trailers. I bet over a year I lost a few hundred bucks of little stuff. Does not happen with the enclosed. Plus, let me tell you, resale of a used open trailer and enclosed, you get more money back on the enclosed. The 12x6 single axle, I paid 1500, put about 500 in it (brakes and some other stuff), when i sold it I got over 2k, so it was a win,win,win. Money is tight, but if you insure your equipment, you might find the ins. is much less if you use the enclosed trailer, it is about 25% on my thieft ins, and that pays off every year!!! Whatever you get, take care of it, lube it and be safe!!!
