The Bailey Discovery range a few years ago had a 2 birth fixed bed as it had no bed slats as standard so the front lounge can't be used as a bed. Not sure how many we're built or how many are available for sale.
The layout was the same as the Ranger 460/4.
Sprite Alpine 4 & also google Adria, Sterckeman & Caravelair, will give you a few to look at. Although a small 2berth fixed bed will actually be 3 berth because it will have 2 seats/table that converts to an extra bed but most owners will just use this type of caravan for a 2 berth.
This is the Caravan you will be after we brought this in 2008 Bailey Discovery Mercury 2 Berth with bunks at front and they have been reinforced so our Grandkids could sleep on at the back a Fixed Bed .
Unladed Weight 910KG
Laded 1130KG
But a lot of caravaners class them as a four berth but in the Manual from Bailey they do say it a 2 Berth Fixed Bed and it is awesome in a couple of years it will be up For Sale but this van has had a lot of extra"s put in .
Our friends have a 4 berth sprite alpine, in my opinion it's more suitable as a 2 berth, how they fit themselves, 3 teenagers and 4 dogs in it I will never know. It would be an ideal layout for a couple tho that need a fairly light weight van
