The issue with modifying the blower to go slower is not enough airflow to close the sail switch. The PWM board will allow you to slow it down to just above the point the sail switch makes.
It also partly depends on the heater capacity, if it is ducted etc. My heater is ducted and small enough to use a lower CFM fan, so it only uses about 4A when running and is very quiet. My inlaws, even with a trailer smaller than mine, have a non ducted unit that uses over 8A when running.
Also, that battery chart really reflects the desire to obtain the maximum number of charge cycles, like 600 or so. For people like us occasional campers, our batteries will never see that many. So if I shorten the life from 600 to 250 by discharging to 30%, so what. I only camp a dozen times a year.
