Eddie, I can understand the leak, it happens. Nasty to walk in to but there you are and it's an easy fix compared to the other obstacles you have hurdled.
Now the electric heater is ok for a single family, I had one 40 gal for years and never ran out even with the girls in line. I'm concerned that additional electric heaters will not have the necessary recovery to supply the demand in the morning when you get all the sites rented. When using campsite showers I have heard the familiar oil burner running behind the wall, no lack of capacity there. I sure hope my sister doesn't vist you, she can kill any water heater.
As for the trophy room, well, I notice you have never been married, no MIL trophy.
Seriously, you and the help have done a bang up job. Not that it means anything but I'm sure impressed.
Thanks so far for all the pics and editorials, they are entertaining and educational.
All the best,
Martin
