Totally INCORRECT information
Totally INCORRECT information. I have spoken with people at InterVac Design and they have told me that the CS8 CANNOT be used with the VacPort. There is NO connection on the CS8 for the VacPort hose to connect to. Rather, eTrailer has TWO (2) options. The CS9 and the CSRM both have the correct connection. The CSRM has an extra circuit board that causes the unit to automatically start when the VacPort opening is lifted and the CS9 does NOT have that circuit board requiring manually turning on the unit when the VacPort is to be used.
