Bottom line, if it makes you happy, use the bridge, angle, collapsable support whatever you call it, go for it. I drove around for many years with one, after realizing it was more trouble than it was worth, I canned it.....my process ........is simple, hook up both ends, the outlet from the rig is always higher than the sewer connection...Dump the black tank, close the black tank valve....now this is the only time the deadly black sewage sits in the hose (for a minute) next comes the soapy grey water, the force pushes the remaining black water through the hose.....after the grey tank is empty ( here comes the hard part) I close the grey valve and lift the hose a little getting the remaining Grey water out of the hose, a quick flush, and off we go....I did use the Camco version I think for awhile, but it was more of a PITA for no benefit ....lifting the hose to clear the Grey water is easier than setting up that bridge support thing, and for what....?
