never ran a RV in the "real world" only played with them on a carpet remnant in a parking lot , so i don't know.
but if you run a 2 man crew, a roto scrub with a VCT pad or scrub bonnet followed by a flush/rinse extract is hard to beat
and if you don't have a rotary, get one.
For all they cost, I think they're one of best values for versatility and bang for the buck
