Is this odd?

After camping, when I go to empty the tanks, I have to pull the passenger side of the camper up on two to three layers of my Lynx levelers to get the tanks to adequately flush out.

I have checked at the last few places I have camped, and their dirve-ways, by the dump station, have been slated away from the tank side. But I have a feeling that if I found a level dump area, I'd still have to lift up the passenger side a little.

I often wonder if the slope at dump stations is intentional. It is certainly wide spread.

Odd, maybe - but I wouldn't be too concerned about getting those tanks completely emptied. Normally I'll drain them as much as I can, then I'll add a few liters of water, drain again, add another few litres and some of the treatment products (the blue stuff) and leave it in the tank. The sloshing around keeps the crud from getting too solid on the sensors & the sides of the tanks. IMHO, you should always keep a bit of liquid (clean-ish liquid) in the tanks anyway..

I have to agree for the same reasons...., and it also helps keep the valve seal from drying out and sticking. Some of the newer treatment (non-formaldehyde) chemicals act as a lubricant as well. I use a product similar to this: http://www.campingworld.com/shopping...-bio-pak/27871

The negative slope is because non RVers just dont understand... that said I always raise the passenger side of my RV at the dumpstation anyway just to get a better evacuation.

I imagine it is by design, just like a road it is crowned so when it rains the water flows away and does not pool or flow down the dump hole. Not ideal by any means. When I look at my tank though, the drain hole is in the center and slightly lower than the rest of the tank. Not sure how unlevel is too much for it not to drain completely, but I would think it would have to be quite a bit.

You will not get all of it out.
Use a chemical freshener and put about 2 gallons of water in it, driving will slosh the rest of the crud off of the insides.
I would agree that it is sloped away so it doesn't fill the underground holding tanks with storm water.
