thanks all for your comments, not keen on having ports on the outside as i prefer to have the reels fixed down inside, when i first started WFP i used to lift them in and out all the time, used to do me back in.
i do like the idea of them guides in the floor. i would imagine there quite easy to fit as well, as of yet iv not had any problems leaving rear doors open, but im always a bit anxious about doing so.
so yeah the guides are the way to go
thanks tony
