How long of a trailer do I need (suggestions)? I have 2 scags 61" and a gravely ztr 48". I am wanting to buy an enclosed trailer? Any suggestions on this. Any regrets about certain things after you bought an enclosed. I have some large apts contracts I am afraid of leaving things on my current angle iron trailer for an entire day while we are on the opposite side of property for example. I was thinking about a gooseneck 18'er.
