Cassette Toilet vs Conventional RV Toilet

I know this is an old thread--but--I have only just found it (or been interested to find it)-----We travel in Europe and have had several RVs (5ers & truck campers) and until our latest A class---a German made Niesmann+Bischoff have always had black tanks--we carried a wheeled dump tank, a 3" hose and a Flojet with about 90ft of 3/4"? hose in 3 sections---( we had a load of 1 1/2" lay-flat,but found that a PITA to stop kinks)------on most trips--not using camp grounds--that we found ground level dumps about 50% of the time--the rest we found WCs (or raised dumps---common in Europe) close enough to macerate into, have not used the wheely thing since we lived on c-grounds.
Our present van has a cassette and it was one of the things that I had to compromise on----We have a proper made storage locker for the second cassette----so it is easy to slip one out and the empty one in-------but we can still go less than a week before finding a dump place-----a lot of public toilets in Europe now forbid cassette dumping--probably because there is no hose to clean- up any 'spills/splashes'----------I am looking at changing our cassette for a 'proper' toilet as I VERY MUCH prefer it.
On our extended trip in US---inc. Texas and Alaska with our TC we never had problems dumping our tank-----and rarely stayed on c-grounds.
