Shower clog or something else?

Some RV's use a "Hepvo" or similar inline seal instead a traditional 'P' trap. The rubber "flutter valve" seal opens when there's sufficient flow through it, and it's normal to see some retained water in the drain. As the valve ages, it can get stiffer and retain more water than when new.
Hepvo Waterless Valve
Likely the problem. If you have room to replace it with a P trap, that would be good.
