Problem: Summer time when the fan kicks on blowing hot air into the cab.
Solution: Block Off Kit $59 or.... $4 at your local Dollar store to purchase a giant pool noodle. Note, there are 2 sizes: A small one for $1 and the biggie for $4. Get the big one.
Installation: Remove hood scoop followed by the storage tray. This gives you access to the giant crack between the cab and the hood bonet. Cut noodle to length outside to outside of the A pillars. Slide noodle into one side and tuck it in as you go, just far enough to allow tray to fit properly, sliding other side in as well. Reverse disassemblly ( put it back the way it was). You can also use the cut off part of the noodle to fill in the side cracks.
Result: Definately less heat coming into the cab when the fan is running.
Advantage: If you ride with WV Rider, AKA -" The Duck", any flotation device on your machine may be a great benifit.
