Turns out my cart won’t fit in my trailer unless I go to the trouble to take the seat off. So I am looking at options for carrying it on the back of the trailer. I would love to see pictures, if your setup as the only threads I found were very old and had broken pictures/links. My trailer won’t work with a receiver sadly and I haul with an SUV not a truck. I have seen the one company that seems to still make them and have emailed them to see how they attach.
