Is it legal to modify the box of camel trailer?

It depends on how to modify it. If it is okay to modify the interior space of the RV, if it is to modify the shape and power device of the RV, it may involve illegal issues.

RV, also known as "home on wheels", has two functions, namely "house" and "car", but its attribute is still a car, and it is a mobile vehicle equipped with necessary facilities for home.

RV is a fashionable facility imported from abroad, and its home facilities include: bedding, stoves, refrigerators, cabinets, sofas, dining tables and chairs, toilet facilities, air conditioners, televisions, stereos and other furniture and electrical appliances.

It can be divided into driving area, living area, bedroom area, sanitary area and kitchen area. RV is a fashion product that integrates "food, clothing, housing and transportation" and realizes "traveling in life and living in travel".

All RVs can provide a very important feeling, which is to make you feel comfortable and convenient at home. Because it has a fairly complete water supply system. Without this system, today's RV tourism activities would not be so prosperous.

Water supply system and wastewater system coexist, which can actually be regarded as the same system. The water supply system must be as convenient as home. As long as the tap is turned on, the water will automatically flow out. The clean water comes from the clean water tank installed in the car or the faucet in the camp.

The water in the water tank in the car is 12V automatic pressurized water supply pump. When you turn on the water pump switch, it will pressurize the whole water supply pipe in the car to 20 ~ 40 PSI. Please remember to turn off the water supply pump switch in the RV when it is not in use.

Because, if there is no water in the clean water tank, the water supply pump will always idle, which is easy to cause damage. Before connecting the external water pipe to the faucet in the camp, please fill the water pipe to reduce the amount of air entering the water supply system. Venting air from the water pipe is a simple and basic water use procedure.

Fill the fresh water tank with water first, then turn on the water supply pump, and then turn on all the faucets in the car at the same time until there is no air in the flowing water. When using external water sources, this basic procedure must also be carried out to exhaust air.

Due to the general household tap water supply system, the pressure is very high (100 psi). When using external water source, there must be a pressure reducing valve to reduce the water supply pressure, so as not to damage the original water supply system (40 psi) in the car.

Many new cars are equipped with this kind of pressure reducing valve before leaving the factory. If there is no pre-installed pressure reducing valve in the external water connection, just install one on the "external water connection pipe".
