Ladder rack

I just purchased a Chevy Express similar to the one pictured with the same roof rack. Does anybody use a roof rack like this, for more than 2 ladders and how do you set it up to be easily used. I had a similar rack years ago and could never get on with it

I think these are pretty decent racks.

I installed the Universal Van Racks on my 4Runner and they’ve held out well over the last 2 years, only cost about $400. I guess it depends how many ladders you carry around.

we use WeatherGuard (Maybe WeatherGard?) ladder racks on Astro vans. They work excellent. We also strap our ladders down using steel cables (Krytonite brand) found at Lowes. No bungees here. Too much of a risk.
