Frequently Asked Questions
- Can I keep my sliding windows and still use a accordion boot gasket?
Unfortunately, no. The slider windows must be removed because the accordion boot gasket requires a clean flange or wall to attach. Sliders block access to this area.
- Will a accordion boot gasket reduce road noise?
Yes, the air-tight seal created by the accordion boot gasket helps block wind noise and some road vibrations between the cab and camper.
- I am wondering if the compression boot can be trimmed to fit around the third brake light?
You cannot cut the boot to fit around the 3rd brake light. Here are a couple of things you may want to do.
- Remove the brake light and cover the opening with a thin plate.
- Instead of installing the boot to the shell, install the boot into the truck window opening. Do this only if you remove the rear window.
