Hi all,
I have a 1991 westfalia in northern California with an R410A air
conditioning system. I am trying to maximize the effectiveness of the air
conditioning and wonder if other folks can weigh in on the various window
films people are using in terms of effectiveness in reducing the solar heat,
possible reduced visibility day and or night and or interference with radio
or phone usage.

Also if you have any suggestions for brands of window film that would be
great.

Thanks.

Kevin
