We have two 10 foot sections of Rhino. Really nice that it only extends as far as needed as opposed to the cheaper hoses that will open up all the way. We also have an electric macerator. I couple that up to a 100 foor 3/4" hose when I have no choice but to dump at home. Works real well, I was pleasantly surprised. Original plan was to run an extension pipe to my tank, but the topography doesn't work out. the rig is too far from the tank to get a good flow. This just works. I could take it with me to use at dump stations where pulling a large rig in is just not feasible. Only issue is I need a third 'black hose' to make this viable. So far we've not had an issue.
Do remember to get and use a clear section to make sure what is coming out is actually clean! We've taken to dumping several buckets down the hatch to wash the tank, although our new rig does have a tank wash, and we added a valve so we can close the hose off and reopen the grey to back flush the black tank. The additional security of the end of line valve is also nice. a few years back I was pulling the electric cord out on our Itasca and snagged the black valve, pulled it open, thankfully the cap was still on and it was only a weekend. I was able to take care of this potential mess and effect a clean dump by using some large diameter pipe that fit over the outlet and a couple buckets. Adding the vale occurred the next day!
