Slatted wooden bed frame (Alverstoke)

No longer have my beloved camper van so starting to convert my smaller version. My camping bed doesn’t work because of the uneven floor, but I can alter a wooden bed (make it narrower, change length of legs) to make it fit. If anyone is throwing one of these out (any size) this would be much appreciated. Don’t need mattress but can dispose for you if needed. Thanks, Julie
