I haven't, but this type of problem has occurred on main slides as well and other brands. If the damage is minor, there is epoxy that can be used to reinforce the wood so screws will hold. If damage requires replacement of the damaged wood, then at least all the repairs will be hidden under the bed (although removal of the mattress and bed frame will be necessary).
If you don't get any replies here, you might also post on some of the general RV forums.
