Someone gave me a Readers Digest Household DIY manual.
As a tradesman I thought "Bloody gash..." but I had a look through it and was pleasantly surprised. It is excellent for information on any trades you aren't familiar with... and fitting out your great beast isn't much different from fitting out a house!
So it'd be worth having, I think. It is a great fat volume - 500 odd pages and lots of diagrams, facts, figures and tables. There seem to be plenty of copies on ebay and Amazon. The one on the link is newer than my copy.
