the new T5 kickstarter had a -package of deckplans incluided that might prove useful
theres also a really sweet book of deckplan geomorphs that is a **FREE** download, it says unofficial, but Marc Miller has approved it being distributed, it just cant be sold.
I was the one who took it to Marc for verification of permission, and can provide such if ever needed. its not my work, I just happen to talk to Marc a fair bit, usually by accident
