99% of the time, dumping is NOT a dirty job, it's just a job, its part of the experience of owning an RV, regardless of what make, model, style, or year you have. You can make it a dirty job, or do it smart and never have any problems. I've not had any problems dumping my TT in years (and I do not use gloves). But the 1% ... accidents do happen.
This last Summer we were at a KOA in Georgia. A CLASS A MH pulled into the site beside us. We were staying 3 nights, he pulled in just for an overnight.
As soon as he set up, he started pulling everything out of one of the MH's bays, where the tank valves are. He told me earlier in the day he discovered one of the valves started leaking, and .... you guess it ... all that aromatic odor filled the coach. He and his wife had stopped earlier to wash out the mess, but since they reached their destination for the night, they needed to dry everything out now. And by the way, there was nothing wrong with the valve, he just did not close it completely after the last dump.
In this case, that 1% ... yes, this was a dirty job. Any time there is a spill, it's not pleasant. But if everything is done right, take your time, take a bit of normal caution, check all your fittings, and hose everything down when your done, it's not dirty! It's just part of RV ownership.
