i ordered our customline without a ladder as i thought they were a bit pricey for what u get , so Ive been looking around and Whitworths [ boating shop] sells tubular telescopic ones which look really good

Ive seen these in a DVD and they swung in under the matress when not in use .

$149.00 for the one at Whitworths
I would hate to hear what Customline were going to charge you
