Bosch Instant water heater

      The water heater project is coming along slowly, this requires extra reinforcement on the trailer interior wall with another layer of 3/4" plywood, between the regular 3/8" plywood walls. I am also making a water heater cover from the metal plate, same as the tool box in keeping with the stealth look. The top flap of the water heater will flip open, this will allow the unit to vent properly when in use. Here are some pictures of todays progress. Besides never having worked with metal, I have also never hooked up an instant water heater, much less a propane model. If you have some tips, now is the time to let me know :-))
