All this talk about heaters. Here's a twist. Go and get yourself a heater
only if you drive a real beater or long to. If you fancy them and would like
one, consider this.  A guy with a nice bus gets a swell gas heater. Now he
can drive on even the coldest days and stay warm. Cold days, snowy days,
salty days, rusty bus...Soon enough the nice bus has extra ventilation in
the rockers, wheel wells, floors, etc and now you really need that expensive
gas heater with the cold blowing in.  I am assuming of course that your bus
has lasted long enough to rust from being winter driven and has not already
gone up in flames!  Those burning busses really drive you out with all that
heat.
    This is all tongue-in-cheek of course and I'm probably just jealous I
don't have the heater, but my suggestion is to save the money and go to the
army surplus and get some REALLY warm gloves, etc. Better yet, I garage the
bus in winter and use that saved insurance $$ to fix it up some more. There
are plenty of $500 Ford-n-such winter beaters out there ready for 3-4 months
of abuse. Have fun all!
