My trailer came with the lift kit standard but the gas springs were way too strong. The bed would lift with one finger but you almost had to climb up and sit on the bed to close it. They put so much pressure on the lower attach brackets that the bed frame on one side broke. I did a repair job and replaced the springs with ones half as strong. I googled "automotive gas springs" and found more information and suppliers than I could read. One thing I found is that when you don't have to pay for the"RV" name things are much cheaper.
