Slurryquip will bolt on to the chassis , do not hang it out of the back door , it is a disaster.Lovely set up. Unfortunately ours would have to be door mounted from slurrykat as the tanker doesn’t have brackets from the factory. It’s 6 years old now. I’ve got a quote sitting here. One black mark for slurrykat which is totally bizarre is there is no lights on it. Every other brand has them on the bar.
