"Roughing It Easy", volumes 1 and 2, were originally published in the 70s; this book is a combination of those two books in a "slick" package, but some of the information has been updated very little, if at all, and, in some cases, is still impractical or too complicated for most families. The "completely revised and updated" statement on the book's cover seems to refer to a section on solar cooking (with detailed instructions on constructing a parabolic-shaped solar cooker) and an "updated" recipe for s'mores. Most of the illustrations and several of the cooking/camping techniques are from the original editions of the books, and more than one shows its age - a wooden crate (p. 36 - haven't seen one of these in years); cutting "green sticks" for cooking? (hardly environmentally sound and illegal in all public campgrounds that I know of); aluminum muffin tins for open-fire cooking? (the light-gauge aluminum now available melts too easily for this technique); tent illustrations and other product-content descriptions that are outdated and non-specific (no dome tents? no specifics or name mentions on "synthetics", e.g., Polartec, Quallofill, Supplex, etc.); thread spools on a coat hanger for hot dog, etc. cooking? ( p. 140 In the 70s, wooden spools were available, but they've been plastic for a long time now, and wire coat hangers usually have a coating on them that can be unsafe when in contact with food).
The "new" book also leaves out some of the better recipes that kids like, e.g., "campfire stew", but includes heating a TV dinner! The recipes rely heavily on additive and preservative-laden "convenience foods", and canned foods, and fresh vegetables/fruit are rarely mentioned. And, my favorites, cooking on the car manifold, cooking hamburger on a shovel and hot dogs on a pitchfork!
There IS good information in the book - the old "tin can" stove, fire building, "oven" baking, different cooking techniques, and several other things - but impractical ideas and "equipment-rich" or complicated techniques, e.g., the "vertical spit", pp. 144-145, are too common.
Unfortunately, there are few, if any, books of this type available to the "novice" camping public; the book's continuing popularity confirms this. Perhaps a thorough "update" and revision of the book's material, photographs, and techniques is planned; it would be welcome, in my opinion.
