why do you need to match a RV water heater as it is never seen anyhow

As far as matching- its matching the color of new heater door to campers exterior.
Which if replacing an Atwood water heater (larger), cut out size is different and new door required to retro fit.
As to OPs question I haven't swapped. But my brief research left me with thought is it wouldn't do what I was looking for, instant hot water.
It would on initial fireup supply hot water sooner-not having to wait for tank to heat but time between opening faucet and hot water delivered same, might actually be a longer wait. And also concluded might see slight increase in water use.
Endless continuous hot water for the 2 of just not a need, which seems to be biggest plus. That and end point use-say in residence or large coach, but doesn't apply to small camper IMO.
As little as our heater lights, if just using momentarily throughout day, not sure on gas consumption. Depends on hot water usage and would vary. I just didn't see justification-
However I did note 3amp 12v power use. Constant stand by draw of control boards .2 amps could be minimized by tying to water pump switch. But the 3 amp in use draw every time water turned on gave me pause.
Physically installing not sure what would be involved to retro fit/plumb-its a bear accessing back of ours. Which I also noted the flow control valve-if its as appears, on back of heater, and if need arises to adjust-just not practical.
Overall, given the price and complexity of unit itself compared to tank heater, added 12v use, questionable gas consumption savings nixed the whole idea. The remote pretty cool though. Just my observations-
