Harbor Freight Trailers for Rafts

So I know this topic has been covered a little bit in other posts, but I still don't feel like I have a yay/nay on if it's actually a viable/good idea.

I have a 14.5' SOTAR and am not sure if it will fit on the platform you could construct on one of these.

If you've used these or made a conversion, please post pics / raft + trailer dimensions and let's see it!

Thanks a bunch.

Here's a link to the trailer I was thinking about...
