Oh blimey, well not sure how good these will be, but just had a trailer hired this past weekend, so quite fresh in my mind! It was an Ifor too.
We: I think!
Reversed car into right place.
turned handle to lift jockey wheel up, then moved handle again to lock it into up position off the floor.
Kept turning main handle, the trailer visually lowers, down and down until it is onto the tow bar, then kind of clunks into place.
attatched safety lead/clip thingy onto little hook part of tow bar.
plugged in plug for lights.
released brake.
Then we were off! I'm pretty sure that was it, but hopefullt some seasoned tower will be along to put me right!
Good luck with your new trailer, will be after one myself now I know I can do it successfully!
