Np. Maybe the seals they’re using now are better or different. But when I had mine installed it was just a regular seal rated for less than 150lb weight and then they doubled it at the cab. And the GFC hit my cab third brake light. Had to reposition it initially too. If you have a friend you can also lift it but not for long periods of time. Ever since I changed to the ones I posted I’ve notice no intrusion. Colorado plastic seems to be to the task. Michigan roads are the equivalent of off road everyday lol. The road I live is riddled with 6” deep potholes.
