I bought Sar Major walls for the roll-out awning on our Jayco Pop-Top caravan about 10 years ago. The van and it's annex has parked on sites from Perth to Brisbane (and most places in between) over the years and never needed attention. Mind you I've lost or bent plenty of pegs. When we upgrade our van later this year we will definitely upgrade to new top of the line Sar Major walls
Approximate cost: $1500
