Well I have decided to buy an enclosed trailer to haul my k1200lt. I've narrowed it down to either a 6x10 or a 6x12. I can only fit one bike in either one so I'm not sure why I'd spend the extra for a 12' (about $200 more). What am I not thinking about?? Any suggestions on which trailer I should go with?? I don't want to regret it after the purchase.
