  • Required Mounting Depth For Mighty Cord 5th Wheel/Gooseneck Wiring Harness On 2020 GMC Sierra 2500HD
    The Mighty Cord 5th Wheel/Gooseneck Wiring Harness # A10-7010 requires 3-1/2" of clearance behind the mounting flange of the 7-way connector. This measurement includes the wiring connector for the 7-way connection. This will be your best solution as the other harness have similar connections and the magnetic EZ connectors require more clearance as the wiring does not 90 degree from the back of the connector like the Mighty Cord.

  • 5th Wheel Wiring Harness for 2021 Ram 2500
    The 5th wheel wiring harness I recommend for your 2021 Ram 2500 is the Mighty Cord 5th Wheel/Gooseneck Wiring Harness with 7-Pole Connector # A10-7010. I really like this harness because Mighty Cord is known for making really durable and high-quality wiring products, and because it is 10 feet long to ensure you have more than enough length to reach your Ram's factory plug. In regards to install, if you already have a hole cut out, you won't need to drill another one. I have added a link...

  • What Gooseneck Wiring do you Recommend for use with an In Bed Camper
    Yes we sure do. The Mighty Cord 5th Wheel/Gooseneck Wiring Harness w/ 7-Pole Connector part # A10-7010 is an excellent choice and offers the 90 degree turn to keep it from hitting the bed sides. I chose this one because the 10' length will give you plenty of cord with out being too short. When routing it you will be surprised how quickly 10' of cord disappears and any excess can always be zip tied up and out of the way.

  • What Gauge Wire Is The A10-7010 Mighty Cord Universal Wiring Harness for 5th Wheel

  • Recommended 7-Way Splitter for Second 7-Way Connection for Truck Camper
    We don't have a 7-way splitter like the photo you sent. We instead for applications just like yours recommend using the Mighty Cord 5th Wheel/Gooseneck Wiring Harness w/ 7-Pole Connector - 7' Long # A10-7007 or the 10 foot long # A10-7010. This will allow you have the connection at your bumper as well as a connection in the bed of your truck wherever you choose for a simple connection to your in bed camper. There is no problem with charging your battery for either or both of these connectors....

  • Trailer Connector Recommendation for 2005 Chevy Silverado Long Bed
    I'd recommend going with the # A10-7010 10 foot long version, as my fear would be that the # A10-7007 might come up a little short in length. I've linked to an installation video for the 7-way and wiring harness that you might find helpful.

  • Recommended In Bed 7-Way Connector for a 2023 Ram 2500
    To add a 7-Way connector to the bed of your 2023 Ram 2500, I recommend the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness w/ 7-Pole and 4-Pole Connector item # 41157. This harness puts a 7-way connector in the bed of your Ram truck and allows you to keep the one on your bumper. This makes hooking up to your 5th wheel or gooseneck trailer easier and more convenient. I have linked a couple pictures and an installation video below.

  • Fifth Wheel 7-Way Wiring Kit Recommendation for 2000 Ford F-350
    We have the Draw Tite 5th wheel 7-way kit part # 20031 which is confirmed as a fit for your 2000 Ford F-350. It has the square connector you mentioned to connect into the vehicle wiring. The harness length is 7 feet though which is normally enough to get the connector up into the bed of the truck. For a similar setup that uses a 10 foot harness we have the part # A10-7010 but this ties into the wiring by wiring into the round connector behind the 7-way at the vehicle bumper.

  • Recommended 5th Wheel Hitch Rail Kit for 1994 Chevy 2500 Pickup
    I recommend going with the B&W Universal Base Rails and Installation Kit # BWRVR3200 for your 1994 Chevy 2500 pickup. This gives you the standard base rails that you need to utilize the Reese Pro Series 30056 15K 5th wheel hitch you have. If you don't already have a 7-Way connection in your truck bed I also recommend checking out the Mighty Cord # A10-7010 which tees in behind your current 7-Way using the US Car Connector plug. This wiring makes it easier to connect the wiring from your...

  • Does The B&W Gooseneck Trailer Hitch Fit A 2022 Ram 2500 With Rambox
    Yes, the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1320 is confirmed to fit your 2022 Ram 2500 short bed with 6-1/2 foot bed with Rambox. A quick note, make sure to keep an eye on the clearance between the trailer and walls of your bed because the Rambox makes your bed narrower than normal. The B&W Gooseneck hitch has a gross towing weight of 30,000 pounds and has a vertical load limit of 7,500 pounds. If you need a 7-Way connector in the bed for your trailer, I recommend...

  • Compatiblity of Underbed Pucks and 5th Wheel Hitch for 2015 Chevy Silverado 3500
    For your 2015 Chevy Silverado, the Under-Bed Rail and Installation Kit for Reese Elite Series 5th Wheel Trailer Hitches # RP30868 is a confirmed fit. The Reese Elite pucks have the same dimensions as the Ford OEM pucks so the Reese M5 5th Wheel Trailer Hitch for Ford Towing Prep Package- Single Jaw - 27,000 lbs # RP30922 is a fit. The max capacity is based on the smaller capacity of the two parts so your max capacity is 25,000 lbs based on the under-bed rail kit. I also recommend you...

  • Recommended Curt Fifth Wheel for my 2018 Ram 3500 Prep Package
    For your 2018 Ram 3500 with the Prep Package the Curt Q25 5th Wheel Trailer Hitch for Ram Towing Prep Package part # C16049 is going to be the way to go. While the Q25 part # C16265 is very similar its legs are for industry standard in bed rails rather than the custom puck legs for your Ram and won't fit. These are both however made here is the USA. The Mighty Cord 5th Wheel/Gooseneck Wiring Harness w/ 7-Pole Connector part # A10-7010 will work out really well if you do not already have...

  • How To Find 5th Wheel Towing Capacity of 2010 GMC Sierra 1500
    In order to find the towing capacity of a 2010 GMC Sierra 1500 you'll need to take a look in your owner's manual. This will list the tow capacity for said vehicle based on what it's equipped with from the factory such as cab type, bed length, engine size etc. The towing capacity range is from 4,400 lbs to 10,700 lbs depending on options. In order to tow a fifth wheel trailer you'll need a fifth wheel hitch, install kit, and wiring harness. I recommend the Curt Custom Fifth Wheel Installation...

  • Reverse Light Pin for Lance Camper 6-Pin Connector
    Lance decided to be unique and come up with their own plug which can be pretty frustrating. According to my research the reverse light function should be the pin in the 11 o'clock position when you're looing at the camper end plug head-on. Normally we recommend just replacing the Lance 6-Way plug with an industry standard 7-Way plug like the Hopkins # H20043 and then using an in-bed 7-Way for your truck, like the Mighty Cord # A10-7010, so everything is easier to relate to standard 7-Way...

  • Gooseneck Hitch Options for a 2015 Ram 2500
    The Hide-A-Goose Underbed Gooseneck Trailer Hitch # 9465 is the base unit and the only rails that go with it are for Ford and GM pickups. For your 2015 Ram 2500 we have the following options: Curt - # C60614 B&W - # BWGNRK1384 The Draw-Tite and Curt options have removable hitch balls but the B&W is the only one that allows you to store the hitch ball upside-down like the Draw-Tite you're asking about.I personally like the B&W the most just because you don't have to find a place to store...

  • Auto Slider 5th Wheel Hitch for 2017 GMC 3500 Long Bed Dually with Factory 5th Wheel Package Pucks
    For your 2017 GMC Sierra 3500 Denali with long bed and dual rear wheels you can absolutely still use an autoslider hitch if desired. Since you have the factory 5th wheel prep package puck system you will first need the adapter # DM6206 and then you can use the Demco Hijacker 18,000 lb # DM8550034 or 21,000 lb # DM8550035. This will work very well together. You also may want to consider adding a wiring connection to the bed for a clean look and easy connection point using # A10-7010....

  • Recommended 5th Wheel Hitch for a 2017 Ford F-350 Super Duty Without the Factory Tow Package
    I have the perfect solution for you to be able to remove a 5th wheel hitch from your 2017 Ford F-350 Super Duty truck bed. B&W their 5th Wheel Companion # BWRVK3500-5W which fits into the Custom Underbed Installation Kit # BWGNRK1116-5W. The great thing about this underbed hitch is that it is actually doubles as a gooseneck hitch. It comes with a turnover hitch ball which you can turn upside down for that clean truck bed when it is not in use. The B&W Companion is made to sit in the...

  • What is Needed to Tow 5th Wheel & Gooseneck on 2023 Ram 3500
    To have the flexibility to tow both a 5th wheel trailer and a gooseneck trailer with your 2023 Ram 3500, what you'll need is from B&W, their Turnoverball gooseneck and the Companion 5th wheel hitch that can mount in it. The correct parts are the following, and you'll need either a fixed hitch if you have a long bed or sliding hitch for a short bed: - B&W Turnoverball Underbed Gooseneck Trailer Hitch & Installation Kit for B&W Companion # BWGNRK1320-5W - Long Bed: B&W Companion 5th Wheel...

  • Maximum 5th Wheel Towing Capacity for a 2010 Ram 2500 with 6.7 Cummins Engine
    According to my research, a 2010 Ram 2500 with the 6.7L turbo diesel engine has a maximum towing capacity of 13,350 lbs if you have the manual transmission or 13,450 lbs if you have the automatic transmission when properly equipped. Therefore, I cannot recommend you use this truck to tow a 15,000 lb trailer. If you are able to find a trailer that is within your vehicle's towing capacity then you will need an installation kit and 5th wheel hitch in order to tow it. For this, I recommend...
