As promised, here are some deck plans for a variety of modules. I have not added a key – yet.   They are mostly built from the designs shown in GURPS Traveller: Modular Cutter.  However, one credit goes to a guy called Brook West who posted a design of a Recreational Vehicle Module back in 2002 on the internet. I reworked it slightly and there it is. Your own powered Winnebago in Space.  It comes with a detachable nose-cone that can fit into the cargo bay to aid streamlining.
