Too many variables on how a coach is used, and how it was equipped when bought, makes so many, many different approaches and opinions on what is 'right' for any situation.
Our's is an older coach 04 model, built in Sept 03. As sold, it had propane feeding the Norcold 1200, and the cook top only.
Our Norcold is gone, Samsung conversation, so now only cook top. But, we also stubbed out the feed to the fridge area with quick disconnect to feed a Mr Heater Heat Buddy. When in cold weather traveling and boon docking, maybe 10-15 days out of the last 18 months - we'll use the Heat Buddy in the AM to warm the coach up. Then maintain the temperatures via out HydroHot feed to our two zone system.
We last topped off our LP 14-15 months ago, and from memory used the Heat Buddy for two or three cycles since that refill. With cooktop usage, our tank still reflects Full. (We also have a stub out in the LP tank bay, that we can use for the Amazing Camp Fire in a Can, BBQ, or even outside use of Heat Buddy. But, since I carry a filament sound 20lb tank of propane anyways - I find we use it for these outside usage demands. (Usually want the Amazing Camp Fire in a Can a bit further away from the coach...).
Have that huge, heavy LP tank - with very little usage... Have tried to convince, and still am, the DW into doing the Induction Top conversion. (We have 800AH of batteries, MS2812 and 1200W of Solar - so adequate electric juice.). If we make that change, I'll remove the OEM tank, add a slide out tray in it's place. Put another light weight 20lb tank with flexible hose connected to the LP Shut Off control regulator. For usage with the Heat Buddy inside. And also on this slide out tray, and also with flexible hose, I'll permanently route and plumb from/to out wet bay, a location to permanently mount our On The Go Double Standard softener. (Having the slide out, will make service of both LP and water softener, such easier...). Should shave ~250 lbs from this changeover...).
The only thing holding it up, is talking the DW into the induction top
! And frankly, if she does not bite soon, probably will do so anyway - as 20lbs will last us a long, long time anyways
We are currently in a cycle of 10-15% boon docking, down from when we first started. But I believe that has been just because of our travel cycle lately. Expect this grow back up to our 25-35% range of years earlier...
I mention boon docking vs say shore power - as that mix, can for sure make a difference in whether or not induction tops swap out is right for someone. With our current battery bank, and solar size - I feel more then comfortable with no LP cook top in our coach
So what? Well nothing, just sharing the variables that effect my/our decision process (Especially documenting the DW's preference to LP flame for cook top
!) - as it is a factor for us
Best to all, travel safe, have fun,
