This company is very responsive. They shipped the launching dolly immediately and when I needed parts, sent them right away. Before I purchased the dolly, I called to ask about what looked like it would be a problem. It was a problem. But when I told Dynamic about it, they had the parts (in stock) that would make the dolly fit my boat. Now I (solo) can transfer my wooden boat from the trailer to the dolly, using tie downs to secure the dolly to the back of the trailer. Quick and easy and safe. I’m happy.
