RV Tankless water heaters who has one?

[BMG Coach]

I'm in the "tossing ideas" stage now, & I'm wondering about these. I am wanting to free up some space underneath and go with a tankless water heater. I want to find out who has installed one and whats the cons if any to tankless water heater ownership?

I thought about that when I had to replace my Raritan but it would have required major surgery including cutting a hole in my wet bay door. That was something I didn't want to do. I think they are a good idea for those that have a standard propane water heater rather than an electric or AquaHot unit.

You really need to consider the venting of the heat. If you can safely vent the heat produced the why not other that it would limit your Dry-Camping.
