It's no different from house plumbing. Try a plunger first, then try taking off and cleaning out the U-bend. Finally try chemicals (but make sure you then empty into a proper sewer, rather than septic tank).

very different to house plumbing.
There is usually no U bend but there may be a slight dip on the pipework to prevent smells.
Small bore convoluted waste pipe, which by its very design will cause terbulance and slow water flow and encourage waste particals getting trapped in the convolutions.
Of course, American motorhome plumbing is done properly with domestic type large bore (1-1/2") rigid waste pipe and a proper U bend under the sink and shower.

We have proper u bends and P traps on all our pipes, in a British built van. We do have slow drainage in the kitchen sink sometimes though, usually when the van is down more at the front. Boiling water or soda crystals down the sink usually gets things back to normal

boiling water can be dangerous to plastic fittings and sinks etc, so beware. a couple of bottles of cheap cola will normally eat through a blockage and is not as toxic as drain cleaner or caustic soda. plus its a cheap fix too
