As far as the hose goes, as long as the outlet on the TT is say 6" or so or more above the CG sewer inlet, you can just dump as usual and then raise the hose up at your TT end a bit and "walk" it along the ground to get what's left in the hose out. Way faster and easier than setting up a hose support. We bought a Camco hose support in the very beginning but only used it a few times and haven't used it in years. Still have it in case a CG somewhere ever insists on using them. The majority of folks in CGs that I see don't use a sewer support.
We have two outlets on our TT and I regularly walk it to the 2nd one every time I dump and it can sometimes be full of effluent the entire length. Very easy to do. On the rare occasion that the CG sewer inlet is on the wrong side of a site , I end up needing to crawl partly under our TT so it won't drain back out. But you can buy a cap for the hose end if you want.
The sewer hose supports or ramps are simply a waste of time IMHO plus they take up valuable storage space. Some states or CGs require them to be used but I always see folks without them and no issues. They don't help the effluent flow any better.
