We have a Shamrock. A couple of years old, I am thinking that the one you are buying is a new one. If it is not new, then there is a bunk end seal kit that is available, as apparently some people had leaks. We have never had a leak, but ordered it anyway, because it was free, so why not beef up the seals.
Everything else on the trailer is really nice quality, and we have loved this trailer more than any other we have had. It is light and easy to pull but also spacious when opened up.
We have done a few fun modifications which I will be posting pics of in a few days. I will title it Shamrock modifications, so you will notice it. These are mostly just modifications that increased storage and efficiency.
