I have the John Taylor product on my 4 seater. Works great with light to medium rain. A few weeks ago I got hit with an unexpected tropical storm band, which resulted in the back seat portion of the cover stretching to form a 15 gallon swimming pool inside the Morgan! I now put the tonneau cover in place before covering up with the storm cover. The back of the tonneau gives some extra support to prevent the back seat pool from happening.
