Don't know enough about this topic to say, but it appears it is designed for the pro angler.
We offer Trailex through our dealers, so this was likely one configured for us to fit our kayak models... with our molded cradles. You can not buy that configuration from Trailex direct.
Matt, can the PA be left on the Trailex and garaged for storage between trips without hull deformation? I assume so but just checking.
If so then that pretty much seals my decision to get a single Trailex when I buy my new PA.
