What exactly is your "dry air machine" that isn't getting rid of humidity?
It would also help knowing under what conditions you are having this problem.
Typically condensation occurs when inside surfaces of RV are cool/cold compared to warm and humid air in RV. I always notice this first on windows because they don't have much insulating value, so the glass gets fairly cold when it's cold outside. This causes sweating -- condensation of excess humidity on cold surface.
When it's warm/hot outside, running the air conditioner prevents condensation from forming. An air conditioner works to dehumidify, and also the walls and windows of RV won't get cold enough to form condensation unless air in RV is saturated. Obviously an event like taking a long hot shower in a small space will cause condensation to form for a short period, but the air conditioner or letting in dryer outside air will make it go away in a few minutes.
Perhaps if you can detail what and when it is happening, it may be easier to help. I would recommend running the air conditioner but it may already be too cool for all we know.
