Just moved to 5er in December and it's kicking my butt learning to cut soon enough and running out of clearance on front of truck. Very frustrating since I've been backing various bumper pulls since I was 14 (on a tractor). Wife is learning to give better directions but hasn't figured out I'm giving all I can and it just takes longer to react.
I've never feared a spot I couldn't back in but I'm choosing carefully for now with a fifth wheel.
Can you get a good look on Google Earth to see about room for the front of the truck?
