Thanks Scott! I talked to Jeff Owens and he looked at this thread and had some really good suggestions.
Hey Rickk, I suggested to Mr. Owens that he join the forum as an expert on trailer questions. .... I think his expert opinion could help us all out.
Also I told him I thought it would be a good idea to become a sponser of the site. His sister sent a message to IT, is that all thats necessary?
Back to my trailer or yours he said to give him dimensions and he can make the blocks for just about any setup. If the distance is too tall for wood alone he sells an aluminum beam that you bolt to the crossmember, then the wood bolts on top. Pretty slick!
