We've got an overcab bed. It's a fantastic solution to add tons of space to a short vehicle. But a good chunk of the general background noise I get whilst driving is from the bed above my head. Lots of annoying squeaks. If I push up from the driver's seat while driving (!), quite a lot of the noise disappears. We leave the bedding on there and it does dampen the rattles, but not the squeak that sounds like someone trying to use a worn out and rusty hacksaw.
Any tips on quietening it down?
