Do you use any old type of space heater?

I could see something like this working to heat up the interior of a tin top

Sorry I didn't read the whole thread, but has anybody mentioned a space
heater inside the van?  Set on a timer to turn on 20 min before you leave
the house.  The inside will be toasty warm and hopefully the ice on the
glass will melt.
