The frost line plan works great when in my home area with high dew points and fairly high usage of the liquid from the bottle. I was able to use it the few weeks we did shake down camping but when in dry locations where it is also cold, it does not work to well. My switch over valve did its job on the last campout and the fill station was not but 10 miles away. I've not purchased one of those ultrasonic checkers yet but have tried the infrared temp gun but have had not good luck finding the level. Spring is coming so LP issues will slowly go away for us.
