Tankless water heater

My buddy got one (Furion) with his new RV. Keep in mind that his WH is very close to all the sinks and shower - so he has the best scenario. His complaints are that it takes 20~30 seconds of water flow for it to actually start heating and that it takes too much water flow for it to turn on. So it's very inconvenient when washing dishes and they end up standing in the shower waiting for it to fire up. Both of these result in a lot of wasted water.
He is seriously considering installing a traditional 10 gal WH.

Has anyone changed out a LP/electric water heater for a tankless water heater? I really want to but I want a second opinion.

Tankless needs propane to work. There are many complaints about them.

My question at this point would be; what is the largest Propane/Electric water heater can I replace this new tankless water heater with? The original was a6 gallon unit and I do not believe there is any space available, after modifications to squeeze in a larger water heater.

I'm having to really restrict my options as I look for new travel trailer that DOES NOT have a tankless. I can see zero value in them. If you do the swap, I would recommend hanging on to the original.

Glad I took mine out

…. I had a tankless heater in my regular home, glad it’s GONE… My camping buddy put a tankless heater in his RV& he’s glad it’s GONE….

We made that switch about a month ago, installing a G*r**d water heater. There is an ECO module in this water heater that has been faulty from day one. I am still waiting on the manufacturer to send the new module. In my opinion, I would be hesitant to make this purchase again. This unit has shut down in the middle of a shower. When you turn off the hot water at the faucet, you have to wait as much as 10 minutes before the water heater will come on again, otherwise it has an audible alarm and an error message saying the water at the faucet is too hot. (There is no sensor at any of the faucets.)

I would rather have a regular Gas/Electric water heater. I think they're more dependable and they get hot water to any of the faucets much faster than this tankless unit does.
