+1 on the bike Barn, used it for a year and it works great! Anchored it to the drive way and it has withstood 50 mph winds, rain you name it. I bought the one for a touring bike which had enough room to be inside with it and do a little wipe down. The trike Barn would be even better. It works man.

 

good idea not a antenna fan i bought a powered unit and installed it under the fairing
ride safe
