Today we decided to go ahead and cut into the side of the bus and install the RV-500 water heater. I have to say I was a little apprehensive to mess up our new paint job. I double checked my measurements to MAKE SURE all was correct.
The following pictures show the step by step process:
At this point the metal cutting blade on the skill saw would not reach the inside metal panel so the sawzall helped get it cut.
Here the RV-500 is set in place to make sure it fits right. It fit very snug. It is supported well because it sits right on the floor.
After this we pulled the RV-500 back out and foamed in between the two metal panels around the opening.
