I have a Rapid RAC442S (Front bed only) and the 12 volt fuse box is black plastic, approx. 150 x 100mm and located under the bed on right hand side of the van in the same compartment as the battery charger. Hope that helps.
Your information and that of a lady selling the same model have redirected us to the box I was repeatedly assured by the husband that it was the built in inverter.
Many thanks.
Another marriage saved by the forum and the generosity of vanners around Oz.
Cheers
Liz.
