房車牽引第五輪連接器指南

According to a report by the RV Industry Association, more than 11 million households in the United States now own an RV. And if you are interested in joining the ranks of RV owners—especially if you’re looking to buy a travel trailer or 第五輪—it’s important to know exactly what towing an RV will entail.

Here we’ve put together a helpful guide that aims to answer all of your towing questions. This covers everything from choosing the right tow vehicle to understanding towing capacity to knowing the different hitches. Our goal is not only to educate but to help you feel confident and comfortable when pulling an RV behind you.

YOUR GUIDE TO TOWING AN RV fifth wheel coupler

 

選擇合適的拖車

We highly recommend choosing your RV before buying your tow vehicle. This way you’ll know exactly how much your RV weighs before you figure out how much weight your tow vehicle will need to pull. When figuring out how much your RV weighs, be sure to ask your dealer about both the dry hitch weight (how much the RV weighs when it is empty) and the cargo carrying capacity (the maximum amount of weight you can add to your RV). On average, your RV will weigh 1,500 pounds more once it’s been filled with water, gas and gear.

Once you know your RV’s total weight, then you can look to find a tow vehicle that matches it. If possible, opt to have a tow package added to your RV so you can maximize your towing capacity. If you already have a vehicle that you plan to use to tow your RV, make sure you buy an RV that doesn’t exceed the weight limit that your current vehicle can pull. This is where you’ll need to understand your vehicle’s towing capacity.

牽引能力

Towing capacity is the maximum amount of weight your vehicle can tow when pulling your RV. This number lets you know exactly how heavy your trailer can be. If you don’t know your towing capacity and try to pull a trailer that is too heavy, you could end up in a very dangerous situation so it’s vital to know your tow vehicle’s limits.

To determine maximum towing capacity, you’ll need to find out the vehicle manufacturer's weight ratings and compare them to the weight of your RV. You can usually find your vehicle’s weight rating on the inside of the driver door or in the owner’s manual. If the vehicle's ratings are higher than the total weight of the RV, then the RV is safe to tow.

Another good number to know is the Gross Combined Weight Rating (GCWR). This number is established by the vehicle’s manufacturer and represents the maximum weight the vehicle can handle with an RV attached. The GCWR takes into consideration the weight of the vehicle’s axles, wheels, suspension system, and frame, as well as the weight of the RV. You can also find the GCWR in your owner’s manual, or you can call your dealer or vehicle manufacturer and give them your VIN number and they should be able to tell you the specific GCWR.

故障

In addition to towing capacity, you’ll also need to understand the different types of RV hitches. Whatever hitch you choose is heavily dependent on the type of RV you purchase, so we’ve listed three basic hitch types and their corresponding RV types here.

第五輪掛鉤：

This hitch is specifically used for towing fifth wheels. It is installed inside the bed of a truck and sits above the bed of the trailer. The trailer then attaches to the truck with a kingpin mechanism. These hitches are able to handle a lot of weight (anywhere from 16,000 to 30,000 pounds) due to the fact that the fifth wheel’s weight is pressing down directly over the rear axle of the truck.

鵝頸式掛鉤：

這是第五輪拖車的另一個掛鉤選擇，但這種掛鉤系統不使用主銷，而是使用球頭和聯軸器。有些人喜歡鵝頸式掛鉤，因為它們在卡車車廂中佔用的空間更小，而且比第五輪拖車的掛鉤（30,000磅）能拉動更大的重量。鵝頸式掛鉤非常適合較重的第五輪拖車，例如大型玩具拖車。

重量分配掛鉤：

這種掛鉤系統最常用於較重的旅行拖車（最高可達 15,000 磅），可讓您牽引最大載重。與標準保險桿掛鉤不同，標準保險桿掛鉤將拖車的所有重量全部壓在牽引車的後部，而重量分配掛鉤則將牽引桿的重量分散到所有車軸上。您還可以將此掛鉤與防搖擺控制裝置配合使用，以幫助減少駕駛時的搖擺。

標準保險桿掛鉤：

這種掛鉤系統也稱為承重掛鉤或非承重分配掛鉤，主要用於小型旅行拖車（3,500 磅）。與鵝頸掛鉤類似，該系統也使用球頭和耦合器，拖車的重量直接落在牽引車的保險桿上。標準保險桿掛鉤有兩種基本類型： 固定牽引桿，其中球平台永久固定在掛鉤上；以及 可拆卸牽引桿，球檯可以上下移動。

拖曳房車時的駕駛基礎知識

現在您已經更了解如何連接和管理重量，這裡有一些關於駕駛拖曳式房車的快速提示。

When towing an RV, keep in mind that you have a lot of extra weight and it’s much harder to slow down. Plus, half the joy of RVing is in the journey so enjoy the drive and focus on getting to your destination safely rather than quickly.

Make sure you maintain some extra distance between you and the car in front of you. It’s much harder to stop quickly with all of the extra weight behind you.

拖著拖車轉彎的關鍵在於速度要慢，轉彎時要留出足夠的空間。你需要留出足夠的空間，以便你的房車能夠跟在後面，而不會撞到路緣。記住，拖車越長，轉彎時需要的寬度就越大。

A good tip for reversing is to put your hand at the bottom of your steering wheel—this way your RV will move in the same direction as your hand. If you move your hand to the left, the rear end of the trailer will go left. If you move your hand to the right, the rear end will go right. Take your time and don’t exaggerate any of your turning motions. Quick turns while reversing can cause your travel trailer to jackknife and damage both your RV and your tow vehicle.

When reversing with a fifth wheel, use the same steering wheel tip as a travel trailer—place a hand at the bottom of the steering wheel and move the steering wheel in the direction that you want the fifth wheel to turn. If you’re backing into a spot, try to angle the fifth wheel away from the driver’s side to keep your visibility clear. We also highly recommend using a spotter any time you reverse a fifth wheel. Have a pair of walkie talkies handy so the spotter can clearly communicate with the driver and help direct. A back-up camera is also helpful and can easily be installed if your fifth wheel doesn’t already have one.

向房車經銷商詢問的問題

  1. If you already have a tow vehicle, your first question for the dealer should be if your vehicle can actually handle the RV you are considering. Be clear about your tow vehicle's weight ratings and GCWR. Ideally, your dealer should show you different RV models that will put you below your vehicle’s towing capacity to give you some extra flexibility and assurance.
  2. 其次，請查看經銷商是否提供任何額外或特殊的掛鉤套件。如果有，請詢問是否需要安裝費以及安裝需要多長時間。
  3. 接下來，詢問經銷商是否願意將房車連接到您的拖車上。這樣您可以學習如何自行操作，並確保方向燈和煞車燈與房車正確配對。
  4. 最後，請您的經銷商向您展示拖車重量資訊標籤的位置。該標籤上應該有三個數字：車輛總重量額定值 (GVWR)，即您的房車滿載時的最大重量；空載車輛重量 (UVW)，即製造商直接提供的房車重量；以及軸重額定值 (GAWR)，即車輛軸上可承受的最大重量。

我們希望本指南能幫助您自信地拖曳房車。如果您掌握了正確的信息，並且知道該問哪些問題，找到理想的拖車比您想像的要容易。此外，沒有什麼比帶著您的家一起旅行更美好的了。
