See an ad for a Curt Q20 and no rails. Guy said he sold camper and hitch was used one time. Opinions. I have a Reese Slider and never use the slider. Will the Reese rails fit?
I have a Curt 16 for three years with no problem. It has a slider but I have not need it. There are probably better ones but more expensive. However, I am not sure they are worth the difference. I pull my FW from WI to TX and FL and all places in between every year with no difficulties. No problem with the hitch.
