Extension Ladders and The Dark Knight

So I finally got a new work truck with rack and ladders on top and when I hit roughly 50 mph I start getting this single note tone, (F#) that makes me feel like I’m in a scene from the The Dark Knight.
Of course if it were a “D” note it would be a match with the movie. Now I just have to decide if I’m a villain or the hero… :wink:

Stay Safe!

Yeah I had that too. Whistling in the wind? [MENTION=7230]c_wininger[/MENTION] suggested to put pipe insulation in the rung holes and the noise stopped. But you need to glue them in or they go flying down the highway…

I’m pretty sure you can tune it using some pipe insulation foam.

But I’m also pretty sure that the Dark Knight never uses ladders… Where’s your bat hook and bat cable?

Whoa whoa Jared…I might be the Villain here… :wink:

Love your Willy Wonka quote btw!

I’m an 80’s metal fan, so I [B]always[/B] tune down to D. :cool:
