I use removable window tint that in the winter ,  I remove it to let the
sun heat up the van . Around the month of May I put it back on no problem,
It handles very easy and can be rolled up and put in a tube until I need it
. The tint is thick so it does not tear easy when reinstalling or anything
. I really thought about this before buying the couple rolls I needed to do
the job. I bought it at Walmart a couple of years ago, This made the most
sense because In the winter the sunlight does a good job of heating up the
van interior . This is what I have found to be good for me. In the summer
the ac works better with the tint naturally , Without it the Van is
fighting the heat and the van really never cools inside . Just My 2cents.
