    The seller canceled sale due to shipping not going to arrive in time. Very good seller, I was stuck out of state broken down and I needed a replacement part fast. Very helpful staff. If I was not in that situation I would have been able to wait the extra few days. Great staff. I would recommend them to anyone that needs trailer equipment.

    item shipping was a bit long, i was surprised it didn't ship from Pennsylvania like the seller description but from wisconsin? right product, looks about new. bolts were included, but was sent without the adapter piece to utilize the hidden tow hitch. seller responded to confirm which piece was missing when i messaged them about it, but has not responded in a few days. the lack of adapters for the 1 1/4" size makes it not worth the money especially now with missing parts.
