I have searched and surfed, but have not found any information on the weight capacity of the end beds. Anyone have any information or experiences to offer?
The topic has been discussed a number of times. Unfortunately, the search tool won't bring it up because "bed" is too short, and "weight" brings up a thousand posts on weight of the TM as a whole.
The real practical answer is "They will support more than you and your friends can ever pack in there."
