Find out the weight of the van originally and find out who made the sleeper conversion and call them to ask what it weighs. They should be able to tell you pretty accurately what they added. Then calculate from there. I suspect it's fairly accurate though. For 60" worth of bed, cabinets, electronics etc. that would add up.
