I bought a book by Donavan Lambertus which has a very nice Veridion-class ATV that he created both as a 3D model and as three different deck plans for different variations. It is bigger than the Traveller standard OTU one but a lot better. Can't show you pics of it but there is a YouTube link where you can see all around it and peek inside through the drivers windows: https://www.youtube.com/watch?v=jeKg0ZW9718
