Parking a 5th wheel in a tight driveway

I have a CTD so don't fret.. I have a boat on a trailer that is 34' hitch to outboard props and the tandem is farther back and I can make the turn. I can relocate my mailbox if need be as that is the only physical barrier as we have no curbs. DW is approx 20' wide. As far a s skill - i was backing 53'ers in shop bays with a forklift when I was 12 so I am competent.

Thanks to those who offered constructive advice
