I need these bed ends I have seen holidays annex ones by the photos but I like a bit of variety is their any other company that does these if not, why not ?we all need them but im finding $1000 is a bit to steep for what they are I don't need 3 windows in them one would be fine im looking for the tracks they use holiday annex will charge me $150 for set I know bunning has stainless steel not sure about plastic ones,ive seen someone use material like a banner material and had them Velcro across original privacy screen look great,kept the warmth in and is waterproof,it was all in one piece.so what Im weigh up is stop being a tight asse and pay $1000 not sure if I be disappointed in the material they use or hunt down the tracks pot rivuet to van purchase rubber vinyl stich and run through the tracks,considering last time I camped I use shower screen curtain that did the job but kept falling down due to double sided tape all thoughts will be welcome
