But, there is another problem that was demonstrated catastrophically by a friend with an hunting cabin, it could easily happen in a coach installation as well.

Any on-demand single pass direct fired heater has to have good outside access to vent combustion by-products (exhaust). If you have a simple system that heats for water demand only and the outside temperature falls below freezing. The water heater can be frozen a damaged. (Well, in this case destroyed. His cabin now has an automatic dump that opens when the system is idle in cold weather.

The plan is good, but not all situations can manage a good installation.
Dan Greg's idea was a good one except for the freezing part.
