Chapter 1 Introduction

1.1 Basic Concepts and Features of RV

1.1.1 Definition of RV

As a special kind of car, RV is designed as functionality vehicle with functions of "home" and "vehicle". Through the unique design and structure, it can provide passengers with a comfort place like home. It also can let the passengers enjoy the convenient of RV. Chinese RV market is currently in the development period, and now very young and energetic.

1.1.2 Structure of RV

As vehicles with a additional use, there are many additional furniture measures and corresponding running systems on the RV, which are also divided into several areas. They are usually divided into the following areas:

Rest area: rest facilities, such as sofa and bed, are used for passengers' rest, and the proportion of space is the largest and the most important area.
