This is my second trailer with the Trailair ride pinbox installed. I installed the first one on a Cougar 318SAB and I ordered the Cedar Creek 34RL with the Trailer air pinbox installed. I did a lot of research when I was looking into the pinbox options for the Cougar.
I went with the Trailair ride pinbox because it works in two planes of motion with the shock taking care of the chucking and the air bag the proposing of the tow vehicle to the trailer. With the MorRyde and or Demco glide they only work in one plane of motion the chucking back and forth.
