I timed how many extra additional seconds are added by my two Slee swingouts (without hurrying) accessing my rear cargo area.
It adds 11 seconds to getting in... about the same to close. Even less if in a hurry. Still...it is more of a pain...but an Aspirin-level pain. No Vicodin needed.
The time I find it annoying is when I close it up...only to realize I forgot something and immediately have to open/close again.
Side benefits:
One obscure benefit is...added security!
If I back up to my garage...night thieves CANNOT access the rear, and drawers become a time-consuming prospect for theft.
In a parking lot...backing in does the same thing. -Unless the thief can open them...your drawers (and my tail-Gate lock-up solution) is even more secure.
