Hey Connie, thanks for reaching out!
I recommend going with a Furrion tankless water heater since they are the most reliable and have the highest performance rating. We have this heater with an 18" x 18" door both in Black # FR42TD and White # FR68SR so you can get the aesthetic that you're wanting to have in your RV.
Let me know if you have any questions!
