Backing 5th wheel up a driveway

[jwendell413]

Good day - I'm in the market for my first 5th wheel and have a few concerns I want to run past you.

I have a '21 Silverado 3500 HD Diesel SRW short bed (6.5ft)

I want to purchase a 2013 Keystone Cougar 330 that measure at 37' length and about 13K GVW.

1) should I have any concerns backing it up my driveway incline with the transmission, etc. or should it be an easy day? Do I put it in 4WD for more traction or leave it in 2WD in reverse?

2) should I have concern about the bottom of the 5th wheel backend scraping the driveway before the wheels/axel get to the incline angle?

3) should I get a slider hitch to help with such a tight turn/incline in/out of my driveway?

Thanks for any thoughts and considerations I may be missing.
John
