Hi Drew,
One of the waste product from burning propane is water in the form of vapor. When the vapor touches any surface that is below the dew point temperature it will condense out. So even preheating a pan will put lots of water into an RV.

Also, for extended-stay hookup camping during cold weather where you don't want a lot of windows/vents open, electric plate and induction plate cooking probably helps keep interior moisture levels down - as opposed to gas cooktop cooking.
I suspect the difference is pretty much immaterial when compared with the moisture released by the cooking itself. You're going to get a good bit of water vapor in the air when you make pasta, whether your pot of boiling water is heated by gas or electricity (or wood or kerosene or solar reflectors or....)
Complete combustion of any hydrocarbon will of course result in water vapor and carbon dioxide. (incomplete combustion results in other byproducts, notably including carbon monoxide.) The question to me is how much water vapor is released by the combustion in relation to other sources of water vapor when cooking.
According to one calculation I found online, one gallon of propane will produce about 90,000 BTUs when burned, and will produce approximately one gallon of water (in vapor form) during the process. A typical high power RV stovetop burner is rated at 9,000 BTUs per hour, so will produce the equivalent water vapor of boiling away a little under a pint of water durning the hour. I guess that is more significant than I would have initially guessed, and is likely to be noticeable during at least some cooking operations. Boiling or simmering especially (and, to a lesser extent, most all cooking operations) still produce a good deal of water vapor regardless of the heat source, of course, so merely using an electric cooktop won't completely solve condensation problems, though it may help somewhat I suppose.
