Before Internet, we had books and driving to different RV company pretending to be interested in buying so to steal ideas and construction techniques

Today is so much easier..

Youtube is a gold mine of great, good, bad and ugly video conversions, where in a day you can learn so much..

Pinterest is another place where you may find great ideas or links to other people’s site..

RV Commercial site often have on display their 3d layouts and possible layout combinations..

Blogs and RV club also do offer plenty of ideas and links to all the above

Books.., there are still several out there, but they are overly expensive for what they offer and lots of them are really outdated. Books that I would still consider essential are the ones related to electrical and proper carpentry techniques.. It is hard to learn those by simply watching a picture or a 2 minutes video made to sell you something..

Plus it is nice to have some book on your RV shelves.. 😉
