Insulation is super important to make it through the winter in a little bit of comfort. Having a heater will help, but what good is that heater if it all leaks outside the van.
Also, if you are planning on running a gas powered heater please get a carbon monoxide detector. 99.9% of the time you won't need it, but it's one of those things better to have and not need than to need and not have.
