Many people are worried that the trailer will damage the frame, which should be true, because there are three kinds of brakes for the trailer, which are as follows.
1: There is no brake in the lowest gear, and the brake of the RV is completely slowed down by the tire friction of the tractor. When braking, the RV will completely transfer the inertia force to the front frame through the trailer ball, which will cause some damage to the car with load-bearing body, at least metal fatigue will reduce the strength of the frame. If you choose this grade of trailer, it is recommended that the main vehicle choose off-road vehicle or pickup truck, because only these two types of trailers are allowed to use non-loaded body, which is also commonly known as girder; There will be a set of high-strength chassis under the car shell, and the impact force will be borne by the chassis without deformation. From low to high, you can choose BAIC 2 12, BAIC Warriors, BJ40Plus, Roewe Rx8, Haval H9 and so on. These models meet the highest emission standards, and there are no obstacles to getting on the license.
2. Intermediate impact braking, the braking principle is similar to the braking system of ordinary cars, the only difference is that the brake pedal collides with the extrusion structure. When braking, the trailer will impact the preceding vehicle with inertial force, and use this force to squeeze the brake oil to provide hydraulic pressure for the brake cylinder, and the hydraulic cylinder will jack up the brake shoe to realize the deceleration braking of the trailer. This structure will still cause a certain degree of impact on the front frame, which is easy to cause tail flick for the predecessor; Because the weight of the front drive is mainly concentrated in the front position, the grip of the rear wheel is still not great even if it is pressed by the trailer. Then when the vehicle turns, it is possible that the safety level is still not high because of the thrust of the RV and the tail flick of the front car. Therefore, for the trailer with traction braking, it is recommended to choose rear wheel drive. In addition to the above off-road vehicles and pickup trucks, vehicles can also choose MPV. For example, Ruifeng M5, Datong G20 and Mercedes-Benz Weiting are all rear-wheel drive, and the balance of car body weight can reduce the probability of sideslip.
3. The highest state of electric braking, electric braking is not only the change of braking principle, but also the point where this braking system can realize active synchronous braking. The front car is equipped with a brake synchronizer, and the rear brake system connected with the rear car can adjust the braking force of the RV according to the braking force of the front car; An excellent brake synchronizer will integrate an inertial sensor to actively adjust the output current of the brake through the stroke and rhythm of the brake pedal, so that the braking force of the RV is the same as that of the preceding vehicle. After reaching this standard, the RV will neither push the front car nor push the front car when braking, and will not impact the frame of the front car.
Any trailer equipped with electric brakes can be towed, and the only influence on the body is the pulling force at the start, but the reasonable control of the speed at the start will not cause damage to the frame. Therefore, overseas, you will always see that some cars can also tow a large-size RV, so as long as the brakes do not impact the body, it can be guaranteed to be safe and safe. Choose a trailer regardless of its size. It is recommended to choose a vehicle with an electric braking system. Most RV brands will also provide optional services, and the upgrade cost will be several K. After determining the RV type, it is necessary to strengthen the trailer structure. The strength of the trailer bar installed at the collision beam position is not high. It is suggested that the trailer structure should be fixed at the position of chassis reinforcement longitudinal beam, reinforced or welded with reserved holes, and the safety of towing trailer must be the first.

Tang DM, there is oil, electricity and power, and electricity in daily life can meet the needs of your RV.
At present, the plug-in hybrid SUV with 220V high power discharge is the best choice, and the representative is BYD Tang DM. Towing has no pressure, and the most important thing is to be able to continuously supply power to the RV. The car battery pack supports 3.3KW, 220V continuous output for 7 hours, and can be powered by fuel when the battery is low. The same 3.3KW, 220V output, about 1.5L gasoline per hour.
To solve the problem of electricity, the RV is the real free travel, and it can guarantee the comfort of the whole day without relying on the RV camp. Just find something that can supply electricity. This is the only car you have to choose, unless you can stand the noisy and smelly low-power fuel generator.
Hello, choose a tractor according to the size and weight of the RV. For example, if the RV weighs 1. 1.5 tons, you can easily drag it to climb the peak of 1000 meters at high speed (except for continuous sharp bends and steep slopes). If you want to have a good time, choose something over 2.0T.
Besides the engine, the transmission is also very important. The types of transmissions are manual transmission, AT automatic transmission, double clutch and CVT continuously variable transmission. Among the four transmissions, CVT transmission is not as good as the other three transmissions because it is powered by steel belt. It is considered that CVT is not suitable for towing trailer, and manual and at transmissions are more suitable for towing.
I am a Nissan Sylphy 1.6 displacement CVT gearbox, towing a 1. 1 ton domestic trailer. At present, we have camped at two 600-meter peaks, with a speed of 80 kilometers and an acceleration distance of 100 kilometers. National roads and urban roads are easy to handle.
Another thing to note is that towing a car sometimes forgets that there is a big guy behind it, which is very dangerous. Usually when you don't tow the RV, you will suddenly be startled and think that you are still towing the RV.
I think ordinary vehicles on the internet are also ok, not necessarily off-road vehicles or SUVs, as long as the horsepower is large enough.
If you want to travel for a long time, the front car suggests buying the cheapest type B RV. The cheapest one has few configurations, light weight, low price and may be customized. Water and electricity should be the most basic configuration, even the bathroom and kitchen are not needed, because the weight should be reduced as much as possible and there is enough space under the premise of the announcement of the RV. First, to ensure the comfort of passengers, long-distance travel space is large. Second, the storage space is huge. There will be more and more things on the RV. Try to put heavy things in the front car, such as generators, vats of pure water, outdoor tables and chairs, folding electric cars, various equipment, maintenance tools, flour, rice, etc. The lighter the rear car, the higher the safety factor). Third, the front car can sleep more people. Fourth, this kind of car is also insulated, but the insulation is slightly worse. Fifth, there is enough space on the roof to install solar panels. Sixth, this kind of car can also use the short axle as a private means of transportation. After all, it has less equipment and light weight. The length is 5 meters, only a few centimeters longer than the car.
However, the chassis is preferably Transit, Datong or Rising, with sufficient power, and the diesel version is basically above 2.0T, with low fuel consumption. This RV carries 5-6 people. As far as I know, these touring cars with cheap chassis can be won at about13-160 thousand, which is not much more expensive than the original chassis. So I think these B-cars with chassis are the front cars of the trailer nanny class. By the way, the trailer should be equipped with anti-sway controller as far as possible. I don't think this money can be saved.
Finally, it is recommended to buy two fire extinguishers of more than four kilograms, which are not expensive and prevent problems before they happen. Of course, we don't want to catch fire, but if there is a fire, the fire extinguisher that comes with the vehicle will basically not work. On the other hand, if fire extinguishers are fully equipped, natural fires will often not occur all their lives, but if they are not equipped, they may often be encountered!
A little too much nagging, maybe too much nonsense, please forgive me and have a nice trip!
Don DM, don't explain
It is recommended to consider these aspects:
1- displacement-it's better to be a V6 model above 3. 0.
The purpose of the RV is to travel around the world, and the power is the premise to ensure that the front and rear cars pass through various road conditions.
2- Model-preferably an off-road vehicle
Since we are traveling all over the world, it is not uncommon to see various special sections such as sand, water, ice and stones, and the ability to get rid of difficulties is the greatest guarantee of peace of mind.
3- Recommendation-Toyota Land Patrol is better than Mitsubishi Pajero.
There are many models suitable for tractors. Why only recommend these two models?
For these reasons:
(1) I have used it, I know it, and I recommend it. It is irresponsible to recommend without knowing;
(2) The performance and stability of these two cars are obvious to all. The biggest fear of traveling around the world is that you break down on the way. They are capable of taking you there.
(3) Maintenance ability, technician ability and complete accessories ability in remote areas.
At present, no one may be able to surpass them in this respect;
(4) Fuel adaptability
At present, even Toyota is bullying the No.95 oil mark, and these two brothers are both 92.
(5) cost performance
Would you like to cross the mountains? It's cheaper than Pajero. Dare you drive across this stream?
(6) About domestic cars
The road to development is far away, with progress and speed, but efforts are still needed.
Personal opinion, limited vision, for reference only, don't spray if you don't like it.
None of them are qualified. It is said that it is illegal for the driving license not to draw the total mass.
Off-road trailers or large American trailers suggest large and medium-sized off-road or pickup trucks; European trailers have very low requirements for the front car, and ordinary family cars can also be competent. It is recommended to consider a plug-in SUV like Tang DM, which has a certain four-wheel drive capability, is equipped with a large battery, and is comfortable without worrying about electricity.
