Since I have had zero luck with finding a double trailer I am really debating on building my own trailer.

For those of you who have done it, round about how much did you spend in material? I'm not looking for anything extreme or fancy, just a straight forward double trailer with a box on the front.

I thought possibly about doing an inline double trailer but I'm not sure if my Ultra 150 and GP1200R have the same bunk setup that would work well.

Thanks for any advice and or comments.
