So....... I have a tailgate strut that I bought on ebay a while back. A friend and I who has an MN bought the same one. The link below isn't the exact one I bought but it is the same product with a different label and both this listing and the original one said that the same product would fit all Tritons through 05-16.

My friend with the MN installed his and had problems with the strut clashing with the tailgate itself and not allowing it to shut completely. After seeing that I half fitted it (without actually drilling any holes) and it appeared that I was going to have the same problem. After being discouraged by that I haven't looked at it for a couple of months, but I still would really really like to have it on there.
It looks like Viking Shippy on the forums has installed one and it's working fine which is encouraging
