W&D reversing trailer under drop body
Nice ones. One usually screw up real life reversing when too much space is around 
Here’s a-frame logger reversing to a wood pile on the countryside.
Don’t you find you can pull off 100 perfect reverses that are tight as… then you got like 3 bays and your one is in the middle you’ll make a right mess of it?

glad it’s not only me.
Can i just say that reversing on your good side is not always the easiest.As somebody who has reversed into Tesco Macc 2 lots of times ,blindside is easier,lots of room to line up ,lock it round and straight onto the dock,your using the nearside mirror right thru’ the reverse so there is very little that is unsighted .Doing it goodside is far,far harder just look at the room on his near side.Ive found blindside at a lot of tight stores is actually easier,sometimes more room than expected,give it a go if can do it anybody can!!.
