WEEK

END:

why not get your hands dirty and build a camper out of your own pick-up/car?
here is a short guide about how to do it

this book by ken isaac is just perfect, everything you need to know to start building living spaces on smaller scales and modern living furniture! it is actually a rare edition, but it's now reprinted by Rollo Press and here is a pdf version of it. good luck in finding an original copy on ebay or in some dusty wellfurnished bookshop.
