Its heavy and pretty awkward to store. The van has an L shaped front, side dinette/bunk and an end bathroom with wardrobe. Found a home for everything, except the ladder!
In our first van we propped it up against the bathroom wall when on site and it wasn't in use. When travelling it went on the floor in the lounge. In our new (to us) van it fits in the wardrobe.
Again as above never used ours in any of the eight vans we have had with bunks.When kids were small lifted them in and as they got older they got in without it.In fact with one caravan we traded in i found the ladder for that, still in the loft two years later.
1st and 2nd vans had no ladder for bunk.
3rd one was 3 years old and ladder was still in original wrapping. It was still wrapped 7 year later.
4th and 5th vans had no bunks and kids had flown the nest.
