I have talked to my manufacturer about a hitch for my Landmark 2010 Grand Canyon. They say it is ok as long as I am not carrying over 150 pounds. I want to use the hitch to carry our bikes on a thule carrier. Which hitch would you recommend? I have asked this question before, but I accidentally deleted the answer. You recommended something to secure the bikes. Could you please help again? I won't delete it this time. We have two normal 21 speed bikes and a 4 bike carrier. Thank you.
