Well I'm happy to report that I made it home without any troubles. I guess I'll be limiting my trips to days that are warmer until I've had the chance to investigate my fuel system. Thanks for all the help guys.

On a side note, I got the S250 shelter installed without much trouble with the exception of the fuel gas heater's jerry can siphon tube punching through my canvas top. DOH! I already have one patch in that old top and soon there will be another.
