Why don't they ?

Have more dump stations that are inclined down 4-5 degrees from the curb side down to the drivers side? seems like you get a faster and more complete "Evacuation" with this setup. In all my years I've only seen one configured like this at Highlands Hammock SP near Sarasota. I've seen coaches with levelers jack up the curb side to dump but that's not possible for us TT and 5th Wheel Peeps.

It just makes sense to me.





I know, 1st world problems.

The problem with this is not ALL RV's holding tanks have the drain on the drivers side, the drain on my tanks is in the middle so for a complete drain for me would be to be level from front to rear.

Biscuit you got it right. You do not want to direct ground water/rain towards the sewer connection.
It causes the sanitary sewer to overflow with rain water!

x2 nothing worse than up hill, or having a really high curb between the drain hole and the dump valve.

Yep they say the third times the charm,,, that's what it took for us the get a site having FHU's at the CG just outside of Zion NP , the first one I circled around and drove back up to the office.
Explained the situation , so they sent us out to another one, same thing .
I picked out one that the sewer hose would work with, called the office # and politely asked them to change our CS # to the one we were in.
After much squabble on their end I asked for a manager to come out to our CS.
After he unloaded on me , I said follow me over to the other two sights , once he saw what I was talking about , he just said enjoy your stay and walked off.
I think in reality that little light bulb over his head clicked on, and he finally got it. S&^% doesn't travel uphill without a lift pump ... 😉

Every RV I`ve seen has a slope in the bottom of the tank to the outlet of the tank and then the lines to the valve also has a pitch.

I would guess that many concrete pouring guys/gals have been fussed at for not putting in a pad that is level and would hesitate to slant one??

Exactly! Not all black tanks, just like all RVs, are built alike.

A level pull up area at the dump stations is the best solution. SD knows how to build them. 😉
A level pull up area with just a small portion tapered toward the dump station pipe to direct any spills into it.

My thoughts exactly. Recently stayed at and used the dump station in a very nice little city park in Redfalls, MN. The dump station is right at the base of the little hill leaving the park. Your front wheels had to be slopped up 10 to 15 degrees from the rear wheels. The MH dumped OK, but it was strange.

The four motorhomes we've owned so far all had waste tanks with bottoms that tapered towards the drain.

Solving a problem that does not exist.

I can dump in 5 minutes now with my new Motorhome but when I had my travel trailer, dumping could be a chore. My TT was very low to the ground and half the time the hole for the dump station was higher than the sewer hookup on my TT. I had to continually pick up the sewer hose to "help along" getting the stuff out. Now on my motorhome, the sewer hookup is pretty high and I can't believe how quick I can dump all four tanks (2 grey, 2 black). I can dump 4 tanks faster now than just one tank on my old TT.

In PA, they must think that "stuff" runs uphill. Way too many campgrounds have sewer inlets and dump stations that are high.

My waste tanks all slope to the center so tilting the road in any direction will interfere with proper flow. Just looking at the pipe, and not seeing the tank hidden by the bottom cover, will not tell you which way the RV should be tilted.

Don't expect to use the in-slip dump at Fishing Bridge. They stand 12~18" over the pad. Fortunately, their community dump is well placed.

It would actually be good design. It would also help with the inevidable spills if it drains to the hole.

Unfortunately many parks are not really designed just kind of built as they go. As long as it passes code inspection, they don't really care.

Of course, how many people choose or don't choose a park based on the slop of the dump station road?

PS: I'll second the ones where the hole is above the outlet. This is a far bigger issue.
