OK...First of all, Alistair needs to get another hobby....maybe it's pork
season?? Anyway, I would not use my figure bcuz I did not get to the van
that night until 5:30am for a 4 hour nap. We also spent alot of time(6
people) just chilling in the van and talking so had the heater running then,
also. I guess I need to do another experiment.
BTW-Got my Heater Buddy last year for 40.00 at Lowe's due to a listmember
posting a one-day special.
