I never had to until I had crew cabs. I guess it takes more to get the heat back there. It's really only bad after doing activities like skiing where your clothes get wet and sweaty and start to steam up the windows on the drive home, and it's even worse when you have 4-5 people in the truck.
Seriously.
Mine never fogs up with the bed cap on. One of a couple reasons I use the cap in winter.

According to identifix. If the relays, and the fuse are good, but the indicator light on the button does not come on when pressed, check for power on the White/Orange wire at connector C3368, if there is power there, but the button still does not illuminate, you need to replace the rear window.
