On the maiden voyage with our alliance, delta ML206. Struggling a bit with the on-demand water heater. We mostly dry camp or electric only so water conservation is very important to us. Can’t get the water heater to kick on unless we open multiple faucets at the same time. Then, while taking a shower, the hot water will just quit so you end up with an ice cold shower. Is there a remedy for this?

Well, it sure seems like a flow issue.
Have you tried setting the thermostat to your preferred temperature for a shower and then opening the hot water valve in the shower the whole way while keeping the cold water valve closed? This eliminates any blending and forces the full flow demand to travel thru the heater.
Only a suggestion we have a tank style heater in our 310 RL.
All our previous RVs had a tank water heater. Our new 262RB is tankless. And as BryanValRox suggested, try setting the water heater to your preferred temperature for a shower and leave it there. That was the only way we could reliably get hot water on demand. Ours is set at 115 degrees. When we shower we just turn on the hot water only and the shower stays hot, no cold spots. However, the water doesn't feel hot enough when doing dishes but it's acceptable. Overall, we hate the tankless water heater, but we'll live with it for now.
Wonder if industry will ever go back to water tank vs tankless. I don't think tankless has matured enough at this point
I don't think they ever will, because of gas safeguards. Maybe they can upsize the feed pipe to 3/4? I think Jim has the only reliable solution at this point. If dry camping, then you will be wasting water as you wait for hot water to push through. I would see what it would take to convert your rig back to the standard gas/electric water heater. Everything you need, should be in that space. Let us know if you do and what is involved in making the switch back.

What make is your tankless?
Thanks so much! Will give that a shot this week. We have spent the last two weeks trying to get this new camper functional...so many silly design flaws that suggest Alliance does not think through the most basic issues. For instance, the fixed shower head shoots over my head and the support beams for the battery were placed just far enough forward that you can only fit a single battery. $400 later, we had them moved. It's all so frustrating and disappointing, so your simple (and hopefully effective) solution is much appreciated!
Thanks for taking the time to reply and share your experience. So frustrating!
Contoure AA-6000BTU. Interestingly, we tried to register the product per the manual and the website says the company is for sale.
We had the same issue with our shower head until we realized the slider needs to be one side or the other of the vertical support. After rotating it 90 degrees, we could aim the shower head normally as well as raise or lower it on the tubular support. You may have the same style?
