Just an FYI. If you've watched Wheel of Fortune every night of your adult life and do the same thing every day and see life as a paint by number you're probably not going to understand my dreams.
I'm amazed at how people phrase things as an imperative. "You're going to want to"..."it would be better to". Or "Why would you want to do that?" I'm asking because this is what would fill me with delight. Shed and all. If you don't get it you don't get me. A guy in Arizona screamed his head off at me out of the blue one day before the election. Said, "I HATE people like you." Wow. What kind of person am I?" People who have NOTHING. You should be out there hooked up to some guy and raising a family!!!!"
I have so much more than he will ever know. I nearly died 30 years ago and the little things bring me more joy...I love my solitude and I love my shed, which I renovated last year and turned into a bright happy space.
You're boxed in by your own minds. So eager to turn strangers into enemies.

What you ask for in reality cannot be done with the restrictions you have placed. Your RV electrical service since it is 30A at 120 is only 3600W max you have to work with.
3600W is nothing when attempting to heat a large amount of water in a short time. You get roughly approx 3.4 BTUs per watt, your 30A service would give you a max equivalent of 12,240 BTUs roughly!
So, a electric demand water heater just is not possible in reality.
Now, a propane demand water heater is a different story and would be possible to do. However, it will use a considerable amount of propane (120,000 BTU burner is typical for home single point types). Requiring a good sized propane source, plumbing and regulator. They are considerably more expensive to buy starting around $600.
So, taking this into consideration, I would recommend a different route..
Perhaps you should consider a portable inflatable two or 4 person hot tub/spa..
The portable units do not use huge amounts of electricity, they typically do not use a electric heating element. Instead they use the heat from the spa water pump to heat the water (cools the motor as a bonus).
The downside is may not be as tough as a regular hot tub, might have a short life span.
You most likely would need to use pool chems since it will take a long time to heat the water so you won't be filling and dumping often.
The upside is they are not super expensive, often can be found starting around $500 which will be the lower cost rout compared to other ways of heat a large amount of water in a short time.
