[0002] RVs are often used as a means of transportation for families and friends to travel. They need to have travel functions as well as living, entertainment, office and other living needs. In order to facilitate driving, the size of the RV should not be too large or too high, but when parked, it is hoped that there will be ample living space.

[0003] At present, pickup trucks are vehicles with off-road performance. As RVs, they can improve the travel performance of travel, but the interior space is insufficient, and camping or long-term outdoor life cannot be achieved, and the scrap age is 15 years. If a RV with an ordinary chassis is used as a travel RV, the interior space is sufficient after modification, but the vehicle has insufficient off-road performance and travel performance compared to a pickup truck. Therefore, it is necessary to design a body expansion device suitable for pickup trucks and off-road RVs, so that the pickup truck can have both high vehicle driving performance and outdoor camping scenes.
