Rock and roll bed for Transit Custom

[SSC!]

Hi there folks,

Considering some changes to my custom and wondered what my options are and where is best to go. I have looked at kiravans and Remo websites but wondered is there anywhere I am missing to look. What I am looking for is a full 3 seater bed (on rails preferably) and it must be crash tested as it will be carrying children.

Also has anyone converted a custom before? I've not found much in here but could be looking in the wrong place.

Thanks for reading

Avril.
