I carry 50 ft of 3/4 inch hose while traveling. Another 75 ft at home to reach my sewer clean out. Each length is sectioned into 15 to 20 ft for easy handling, storage and shorter hookups.
I made several size sewer screw in PVC caps with garden hose swivel connecters JB welded in place. Allows me to keep the sewer end connected while on site and not have to worry about the hose coming out during use.
DW often has a better idea of how we are going to park (usually not the same as the campsite designers) for a better view. The macerator makes it possible to pull in and hook up no matter where the sewer connection is.
