The dolly is made by Trailex, not Seitech. It does have the larger Beach Wheels and works very well. Unfortunately it is not in NJ. It is on cape Cod. I am asking $400 If you are interested I can probably get it to NJ later this spring.
I am looking for a Seitech dolly for my 14.2. They are on back order from the manufacturer so I am going the used route. Also, has anyone used a Trailex dolly for their boat? If so how well do they work? Thanks
