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!!

This was a direct bolt on, no drilling required, on my 1996 Ford E350 Motorhome chassis. I was able to double the battery capacity of the coach. Expensive part but well made. I used a floor jack to lift and hold the battery box up while making the final connections.

Great quality. I used this product to supply power to my winch. Required some modifications to fit my application (1.5x4 C-Beam trailer) since it was made to fit underneath a vehicle, not bolt to an open trailer. Very happy with the quality and I am confident this unit will last a long time.

Used this to attach a battery to the railing of a utility trailer. Not exactly what it was intended for, but worked great. Very satisfied. Very thick sturdy metal, and very good battery box. Expensive, but you won't be disappointed in the quality.

Great option for the extra battery. I should be able to transfer it to another full framed vehicle or trailer when I’m done with this truck. Can’t see any room for improvement.

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.

I modified the battery mount to fit my 7 X 14 covered cargo trailer. Added a couple of other pieces to it. Works great.

- TorkLift HiddenPower Battery Mount be Used to Add 12 Volt Battery to 6 Volt Battery BankAs 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 trailer...

view full answer... - Battery Mount Compatibility with 1984 Ford E-350 ChassisWe 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.
view full answer... - 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...

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 recommend...

- Wiring Secondary Battery in TorkLift HiddenPower Under-Vehicle Mount w/ Battery Box # TLA7740In 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...

- Battery Isolator to Use on Promaster Van with 220 Amp Battery with 100 Amp Auxiliary BatteriesFor a larger alternator like what you have we have the Redarc Smart Start Battery Isolator # 331-SBI212 which is rated for up to 200 amps. With this battery isolator, you can transfer power from your start battery to an auxiliary battery without draining your start battery. As long as your vehicle is on and the alternator is supplying power to the start battery, the isolator will transfer some of that power to your auxiliary battery. When your vehicle is shut off, the isolator will separate...

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...
