I have been RVing for more than 45 years, starting with trailers and then to a 40 Ft Diesel Pusher with "toad" for 10 years and have recently downsized to a 25 ft B+ (Leisure Van Libero and love it). I must say I have had mishaps with a 3" hose. (What a Mess.) - but since I got a macerator on my Class A (7 years ago) as an add on and now have a factory installed one on my Libero, I never want to go back to the messy 3" hose. By using a Macerator there is absolutley less potential for mess and the dumping options increase marketly. I have dumped in many toilets directly and in most cases I had to push the effluent up hill and at times as far away as 60ft. At my house I have a permanent dump setup but I could not do this in my situation without the use of a Macerator. It works like a charm and do not have to worry about taking a dumping trip upon return home. (must pump uphill.)
The hose with my Macerator is 21ft, but I carry an extension 50ft 1in heavy duty rubber hose and use as required. I don't find it takes so much longer to dump with the Macerator but I would never use anything less than a 1" hose for this purpose. (Smaller hose = more time.) Like everything, systems have to be maintained. I purchased a spares kit for my Macerator just in case - as Murphy says "if something can go wrong it will."
