I don't know the layout of your piping. Maybe you have a check valve in there and you aren't blowing the line out in the correct direction.

Check valve, interesting... I might have to search for that.
Agree on the oil with compressed air, but it does not apply to me anyway. We don't use the fresh water for drinking since we don't treat the tank and lines to keep them safe. I tried air this year because in the past I've used antifreeze, and the smell never goes away. I still got antifreeze (very small amount, but still there) out when I blew the lines out last night. I have camped with this trailer all summer, and it is still coming out.
I fear that I already have an ice block somewhere, it was minus 11 C overnight (12.2 F)after I returned from my last day camping on Sunday. When I got home I opened the low point drains and tilted the trailer, but the temperature got so low overnight that maybe I plugged them with ice already.
