I've owned my Raptor for about 2 months now and want to get a bed cover. I want to go with a retractable type and had it narrowed down to the Pace Edwards Jackrabbit and the TCUSA Roll Cover. I narrowed it down to these two as they have rail options that you can mount Thule or Yakima cross bars on. I was doing research online and for the Pace Edwards it says the cover impedes the use of the bed extender. I called Pace Edwards to confirm and they confirmed that is the case. Does anyone know if this is the case with all retractable type covers or just Pace Edwards? Does anyone have a retractable cover with the bed extender? TIA
