While it's no where near 15 lbs. on our last trip our 4-5 lb. minnow bucket blew out of the truck, nope not the styrofoam type.
We watched it circle over and over, a vertical vortex, and before DH could find a spot to pull over it blew up, lodged under/between the front of the 5er and top edge of the tailgate for a nano second, then it was gone, sucked over the tailgate and under the 5er, out the back and on to the shoulder.
So yeah, there is huge wind turbulence between a TV and a trailer.
but....that's a HUGE eye opener to read that an entire BBQ grill was sucked out????
We won't leave *anything* unsecured in our truck bed again. Heck, LOL, maybe we should tie down the firewood!
We were scared chitless that small minnow bucket would hit a car behind us and cause an accident and thankfully it went straight to the shoulder. Can't imagine what damage an airborne BBQ could cause.
Did your DD check her tires for possible damage from sharp metal edges?
Glad it didn't cause an accident for ya'll or anyone behind you. And thank you for posting this here so that we can all know to take precautions.
