We had a single hob Tru Induction, now have a built in Dometic.
Doing it over, I would go back to a single hob unit, stored in a drawer.
-- Gives you more counter space when not actually cooking and there is less danger of breaking the top
-- Costs a bit less.
-- Works really well if you have a few hot pads for the pans - heat, then set aside while you heat another pan.
N.B. We find that the countertop/RV units don't simmer very well - at low settings they simply pause and each pulse may be a bit more than you want with a drier mixture. We will be playing with an Instant Pot on this trip.
As always with things like this, YMMV!
