oh and if its a drop and swap…dont forget to take your number plate off the trailer first !!
That was me at Gadbrook the other day, crawling under back of the trailer 
Also, if you’ve got a column tail lift on the back - put it down! Done that as well, just as I was getting my head down “you’ve left your tail gate up drive” 
Do that with a drop & swap and you really won’t be popular.
