Newbie wants to remove B&W Slider from bed of truck

I have a brand new B&W Slider and had the same problem. Turns out it is near impossible to remove it yourself. I had two young healthy lads try and they were able to pull it straight out. First time ever I was unable to lift a hitch by myself. We added some lithium grease and it slides out now fine. I also purchased an engine crane from Harbor Freight for around $200 bucks to lift it out of the bed. Chances are you just need more man power to lift it. New installs are snug.
