my $0.02
first off, look at the site, and plan where you want the Van to sit
some people find it easier to reverse into a site from the left, some from the right
get 2 ways or 1 hand held UHF if you have one in the car already
for the one Directing -
stay calm....................
take your time...............
talk clearly.............
stand in the corner of the site where you want the Van to be...... at the back of the site..........
face the front of the site...........
stay calm............
your left is the same as the drivers.........
your right is the same as the drivers.........
do NOT rush for anyone...............
try not to talk to your new neighbors too much while you are assisting in reversing - they should understand if you say
"lovely to meet you, I will be with you as soon as we get this bit sorted"
as the Driver -
listen to what they say.......
take your time............
do NOT rush for anyone...........
dont try and out think the person directing..........
ask CLEAR questions.............
stay calm...............
if they say "hang on......." maybe someone / something is distracting them..... be patient.........
as
@Dandy said - I was taught to put my right hand at the bottom of the steering wheel, push wheel left to get Van to go right or push it right, to make the Van go left.
(you need to try this with a 6x4 trailer to understand maybe....... DONT try it without a small trailer or your Van on - it wont work, and you will get more confused)
Practice makes for less entertainment for others..........
I don't plan on becoming this years entertainment
I dont know of ANYONE who mastered reversing first time.........
