What to consider before buying

Consider your hot water usage: on-demand heaters like Truma are great for endless hot water but costly. For typical RV use, 6-gallon Suburban or Atwood models offer good value. Check for DSI (direct spark ignition) for convenience, and ensure compatibility with your RV's cutout size and power source.
