Interested in learning how "things" in a recreational vehicle actually work. At SUMDALUS.COM, we offer down-to-earth, educational books about 

RV systems that tell you everything the owner's manuals DO NOT, 

and much more!

Our Books are written for all RV enthusiasts, especially those who are:

• Initially "CONSIDERING" RVing;
• Just "BEGINNING" their RVing expereience;
• Have been "CAMPING" for years;  or 
• Living the dream of "FULL-TIMING."

 That means no complicated technical jargon.  The writing is amusing and informal while still being informative.  Every topic is covered in straightforward English so that readers can immediately 

become familiar with the subject(s).
