Which model cook top is that? Can you tell me where you got it?
Not a very special one. It's the Rosewill R-IC-1500, which I got through Newegg a couple years ago. (Rosewill is sort of Newegg's "house brand.") They were on sale, so I bought two, for about $50 each. We already had a $600 stand-alone induction cooktop, so we knew we liked induction's performance, but we were surprised that the Rosewill performed just as well even though it weighed about a third as much. So we've used the Rosewill in our house for a year-plus with good results, and feel pretty positive about how well the second one will work in the Sprinter.
It's principally an appliance for when shorepower is available, but if you had a big battery bank and relatively short uses, you could run off an inverter with some loss of battery longevity due to the high discharge rate. Note, though, that it'll take about a 2K watt inverter to run it, and there've been reports that some people haven't been successful in running them off modified sine wave inverters. We have a pure sine wave Prosine 2.0, so it'll work, though we still expect to switch to a portable propane burner when boondocking.
There's some bad news in that it looks like this particular cooktop has been discontinued:

which will be no great issue unless you want to flush mount it like we did. The very similar Rosewill RHIC-11001 also seems unavailable, and most of the obvious suspects have sloping control panels. But if you search for induction cooktops on eBay, you can find some models that, at least at a quick glance, appear suitable.
