Mattress toppers work just the same in an RV as they do at home. They come in a wide variety of thicknesses, firmness and quality. Different people have different preferences. Personally I would not spend a lot of money on one or expect miracles. If the RV mattress is poor quality and is not comfortable you might want to consider a replacement instead of a topper.
This^^. It's what most of us full-timers do. A foam topper on an OEM RV mattress is like putting lipstick on a pig. (Yes - I know many people do it and claim to be happy... the mattress - not the pig.)
