Whoever designed the rear lounge bed runners at Swift in this van needs a large garden Gnome inserting in their bottom with no lube.  
 
Two flaming hours I've been at this.  What I discovered is there is no way at all to replace the broken shorter side runner without first removing the other longer side.  Because they thought they were improving the design from the Kontiki from the last century which was dead simple all the slats have lugs on and they slot into a grove in the over complex bed runner design you are now familiar with. Both have to come out so you can somehow pull both forward and wangle them in one at time.  I had to cut a chunk out of the end of one of them as it clearly wasnt fitted correctly before as it wasnt run under the wood surrounds for the Truma housing on one side.  Then I couldnt remember how the wooden cover over the rear of the slats fitted so when I first got them in I had to take it all back to bits again and start again.  In the end I fitted new runners on both sides as the old ones were a different colour. So ill keep the good old side as a spare.
The install is made more difficult by the bathroom sticking out so you cant get a lined up run to fit them in with space to slot in the slat lugs.  None of this on the old van.
So Ive done it. Kind of. I still need to attach with screws somehow the rear wooden panel above the slats at the back and put some stoppers on to lock the slats in place. 
Only taken two months.
