Arctic package?

[Drifty1]

I have one question, what arctic package. I am work camping in Anacortes Wa. and as a lot of folks know we are going thru a cold spell in this area. It seams that I have a frozen water line somewhere between the inlet to the rig and the cold water supply to the kitchen sink that also feeds the water heater. So it looks like if I am going to any cold weather camping I will need to drop the belly skin and take care of the insulation problems that I find with water lines. So my question is has anyone done any thing to solve this problem by adding insulation or other type of fix. So when they shut down our job at the Shell refinery for the rest of the week I left the rig with a full bottle of propane, and the thermostat set at 64 deg. I also shut the water off to the rig so when I get back on Sunday evening I am hoping that I don't have to make any repairs to allow me to have water. As you can imagine I am not to impressed with Montana's Arctic Package!!!
