Last summer we went to my BIL in BC. Has a longish single driveway - house/garage on one side and a fence on the other. Said pull all the way in and park your trailer. So I did only to find out when my Ford super crew and 30 ft tt in tow that horizontal across the yard isn't goin to work - I had got myself into a position where I couldn't back out of the yard. Ended up in a back-up go forward back-up go forward situation about 30 times to get completely 180* turned around in the back yard then pulled out and then backed all the way back into the yard. I'm not sure if that is testimony to good or bad backing up skills.
Most of the time I'm pretty good at backin up - once in a while it's like WTF?
