We purchased a Reese Trifold ramp with 1600lb capacity. We loaded an 800lb bike. When we went to unload... ramp completely collapsed!! Thanks to some bystanders immediate help my husband was soar but unharmed. Bike not so lucky. I contacted place of purchase they referred me to Horizon Global. JOKE!!! All I'm looking for is a refund for defective ramp. (no other expenses that we incurred due to this problem) If I could give them a -0 for customer service I would!! They refuse to help & do not stand behind their product & quite frankly RUDE!!
