Video Transcript for TorkLift Battery Boxes - Camper Battery Box - TLA7740 Review

Today we're going to review part number TLA7740. This is the TorkLift HiddenPower Under-Vehicle Battery Mount, with the Battery Box. This is a custom fit part. It is designed to fit the Dodge Ram 2500 and 3500 trucks starting in 1997. What I would recommend for you to do is go to our website, use our fit guide, put in your year and model vehicle and it will show you how it will work for your application. These parts will let you add a battery that ties into your truck's electrical charging system.

This will not include the battery. You would have to supply that yourself. This is designed to be an extension of your RV's battery when the RV is plugged into your truck and it will help provide extra battery power in your camper or RV to significantly extend the time that you can run on your 12 volt system. It is designed to work with lead acid, AGM, sealed, and gel cell batteries. This part includes everything shown here on the table. It will include this battery box.

It includes the mount itself that clamps onto your frame. It includes the mounting hardware, a nice battery hold down strap, and these 2 pieces are the quick disconnect power connectors, show you how those work in a minute here, and it comes with a nice set of detailed instructions. This nice, sturdy polymer battery box is included. As you can see it has the lid. You just push in on the tabs on the side.

Do that and then pop the lid off and you can see on the inside it's very large, has even a divider. If you need it for a large battery you just put it on the very end. If it's a little bit shorter battery you can just slide it in, helps hold it into place when it's a shorter battery. If you'll notice on the lid right here, there's a couple vents that will vent a lot of the gasses out from building up inside the battery box and also right here, these are vents also so when you put your lid on and strap everything down you get vents right here and right up at the top so you don't have any gas build up in the box itself. This mount right here, this is designed to clamp onto your frame beneath the truck. It's an easy, no drill installation and it includes the necessary mounting hardware right here and, again, the battery strap to hold the battery box down.

Basically your battery box would go right in there with the battery and this would be all up under the truck out of the way. Then on the quick disconnect power connectors, it even makes it even easier to install and remove the battery, because what you end up doing is these will come with connectors that you'll connect to your wiring and it will allow you to, one would be to the battery, the other would be to your wiring on the vehicle, and what you end up doing is just line these up, just like that, and you push it together and it will make your connection. Then, if you need to remove the battery, you can just disconnect them very easily. Very simple to do. These parts are made in the USA and they do come with a lifetime warranty. That should do it for the review on part number TLA7740, the TorkLift HiddenPower Under-Vehicle Battery Mount with the Battery Box. .

Installed this about a year ago and have not had any issues with it. It works as advertised! Its not "easy" to install or remove with my current set up and heavy AGM battery. I likely have to many heavy lines going into the box and then connected a fuse box/distribution box on the outside of the box. I have been off road and have not damaged it at all! Great product to keep the "house Battery" out of the bed of my truck and attached low and out of the way! Trying to figure out if I can mount a second one!! 619125

Review from a similar TorkLift Hidden Power in Battery Boxes


The bracket is solid, but the mounting/securing of the plastic box to the bracket leaves a bit to be desired. It does protect the battery well from the elements, but it does not secure the battery down well. If you wanted to spend more money, you could get a battery box from the Offroad manufacturers that fits within the plastic box and bolt it down, which would be more secure. I’m going to be modifying the bracket and box so that I can attach a ratchet strap in place of the provided strap to make it secure as possible without breaking the bank. Eventually I might take some all thread and clamp down a bar across the top of the battery, similar to some older OEM battery securing mechanisms. 637084

Do you have a question about this Battery Box?


  • Dimensions of the TorkLift HiddenPower Under-Vehicle Battery Mount with Battery Box Part # TLA7740
  • I spoke to my contact at TorkLift about the TorkLift HiddenPower Under-Vehicle Battery Mount with Battery Box part # TLA7740 and they informed me that you would not be able to mount two 6 volt batteries side by side in the box due to the limited length. Unfortunately, the bracket is not sold separately from the box. I have attached a photo with the internal dimensions of the above battery box for you but for an option that will allow you to mount two 6 volt batteries side by side, I...

  • Length of Frame Plate of TorkLift HiddenPower Under-Vehicle Battery Mount with Battery Box
  • I went to the warehouse to measure the distance from the top of the single bolt to the top of the double bolts on the frame plate of the TorkLift HiddenPower Under-Vehicle Battery Mount with Battery Box # TLA7742 and found it is approximately 10-3/16 inches; you can compare that to the dimensions of the frame plate of the HiddenPower # TLA7740 currently on your 2017 Ford E-Series. It is important to note that the HiddenPower # TLA7742 is not confirmed to fit your 2017 Ford E-Series so...

  • Wiring Secondary Battery in TorkLift HiddenPower Under-Vehicle Mount w/ Battery Box # TLA7740
  • In order to prevent draining your main battery when using an inverter at night, I recommend using the Deka Battery Isolator, # DW08771, with the TorkLift HiddenPower Under-Vehicle Battery Mount with Battery Box, # TLA7740, (battery not included). The battery isolator will allow both two batteries in your 2014 Dodge Ram Pickup to charge at the same time and will protect the starting battery from being drained by the accessory battery. I have attached a drawing that shows how the isolator...

  • How to Reduce Sway in 2016 Ram 2500 Diesel Laramie Crew Cab with a Truck Bed Slide-On Camper
  • Congratulations on your new truck bed camper! I'm sure you will enjoy it for many years. Sway is a common issue with truck bed campers which can be reduced, but not eliminated. The campers are not particularly aerodynamic and the sway will increase with your speed and high winds. Even though your truck sits level with the camper installed, you could still benefit from a Suspension Enhancement System (SES). I recommend a jounce-style spring system like the Timbren # TDR2500D. These install...

  • TorkLift HiddenPower Battery Mount be Used to Add 12 Volt Battery to 6 Volt Battery Bank
  • As long as you get the voltages to match up correctly you can add a 12 volt battery to a battery bank with the TorkLift HiddenPower Under-Vehicle Battery Mount with Battery Box # TLA7740. The key is knowing the difference between running the batteries in series vs. in parallel. Your 6 volt batteries are in series currently so you'd need to add your 12 volt battery to them in parallel so that the voltages all match. So the main negative post of the 6 volt battery that you run to your...

  • Battery Mount Compatibility with 1984 Ford E-350 Chassis
  • We have many battery mount options but none that are a custom confirmed fit for your Fleetwood Jamboree RV. For your application, I recommend the TorkLift HiddenPower Under-Vehicle Battery Mount with Battery Box # TLA7726 or # TLA7740. Either one will give you some options for mounting your batteries to the vehicle. Since there is not a custom fit for your chassis, you will need to find a working location and some custom fabrication may be necessary.

  • Availability of Behind the Seat Cargo Organizer for 1996 GMC Sierra 2500 Regular Cab
  • When it comes to a behind the seat organizer for your 1996 GMC Sierra 2500 with the regular cab, Du-Ha offer the Truck Storage Box and Gun Case, # DU10038. This is great to keep items from rolling around and with the included inserts, can also be used to transport guns. As for a battery box, unfortunately our vendor, Torklift, does not offer any under body battery boxes that are a custom fit for GM trucks before the 2001 model year. In this case I recommend taking a look at Universal...
