Just my $0.02 - we use SeaDek material for the transom platforms on our waterski boats. It seems like it's pretty similar to the GatorStep stuff and if so, then I can attest to it's durability. We have guys who put on their slalom ski's on that platform and stand up on before jumping in. It has yet to show any wear or rips and it's going on 4yrs since it was installed on 3 of our boats. Keep in mind slalom ski's have rather large and sharp fins on the bottom plus a 150+ pound guy standing on it, but none of the platforms show any signs of wear or tear. On top of that we have dragged full ice chests, propellers, and even a couple marine-grade batteries across it and it still holds up. Plus it's waterproof and UV & stain resistant. Of course this option won't appeal to those who are looking to use their tailgate as a cutting surface, but it is durable, comfortable to sit on, easy clean up, and it looks good.
