Have pulled with a SuperGlide for 6-7yrs and >50k miles and am very happy with it. You will not notice any difference pulling or backing up other than when backing into a tight uphill spot without thinking you'll have a feeling of relief when the 5er doesn't punch out your back window.
You do need to be fairly straight hitching and unhitching (within 15deg) but we haven't found that to be an issue, just something to be aware of.
More importantly, make sure the pin box rides up onto the hitch a little when hooking up. If the truck doesn't *lift* the 5er a little you run the risk of 'high hitching' where the pin is too high in your hitch and the jaws won't automatically wrap. If this happens you'll know it right away, correcting it can be an issue. I've actually had to pull two pins on the hitch to release the top head to be able to fully unhitch and then do it correctly.
Enjoy your new rig and hitch!
