The problem is they lack the flexibility of what we call the old fashion propane and electric as a back up. In the old days if you run outta propane just switch on the electric my instant hot died on last trip and I did not have the electric element as a back up!

What I learned is that this video confirmed why I never go to camping world for service, or as a dealer or anything other than parts. How did you not think of filling up the water tank, checking to make sure it was lit/on ready to go. Then not knowing to give it time to heat up. Also any manual(and common sense) for the on demand heater tells you it has a time and temp cut off to prevent damage, burn up etc. It's called safety. Those limits are usually in the first 2-3 pages. I'm not sure what this guys job is at camping world but he clearly knows nothing about RV's. Then who decided to post the video of him looking like he has no clue as to what he is doing. It just makes you look bad.

you always talk about tanks dropping out. is that really a thing you cant fill your tank? we fill ours all the time
