I was actually looking at residential (24")cooktops. Hadn't thought about induction at this point. Question...Is it necessary to use something that is strictly for an "RV" and regarding the induction, is it more efficient than say, a more powerful gas top?
Thank you for your replies!
It's not necessary to use something specifically "RV" rated. Some (most) non-RV gas stovetops probably have grates, burner tops, etc. that might be prone to rattling or jumping out of position while driving, but a little inspection in the store should show how much of a problem that is likely to be. Many also require 120 VAC for the igniters and possibly even the basic controls.
For absolute cooking efficiency, that is the portion of input energy that gets transferred to the food vs. lost to the environment, the induction cooktop is superior. How this translates into practical matters is much less obvious. It will for sure heat up the interior of the RV less than a gas cooktop. It may or may not heat up faster than the gas one, depending on the gas burner's power, the heat transfer characteristics of the pans or pots, and other variables.
For off-the-grid use, it's even murkier since they use two rather different fuels. An induction cooktop of course requires either the generator or a substantial inverter setup (with the corresponding large battery bank). On my RV, I can much more easily spare a bit of propane than I can a bunch of electricity (assuming I don't start the generator), so the choice is a no-brainer for me. Of course if one is camping with hookups, or running the generator anyway, electricity is rather more plentiful.
