Just returned from a few days up north in Minnesota.
Some great information guys, thank you.
Just FYI, in 2015 I had a 5th wheel Surveyor with just over 5 inches of bed clearance and while backing into a rough site the trailer swung down and did almost $2000 damage to my 2500HD truck bed. I am really sensitive to bed clearance now!
Tomorrow I will start checking out the information and let you know what I decide on. Thank you.
