Nice heavy duty switch for my RV

Best of all, the bracket lined up perfectly to two existing bolt holes at the top of the radiator mount bracket that my 2016 E450 chasis has (Thor Vegas RV). Didn't even have to drill :) . I can reach the switch easily through the front grill. It's exactly what I wanted to isolate the chassis battery from any drains for the extended down times.

Pros
  • This it a very stron switch
Cons
  • The switch can be difficult to operate, especially for those with mobility issues

Recommend for people who want the best.

Very well designed product. I used it on my Semi to protect from dead batteries while stored. This is a heavy duty well constructed piece.

Pros
  • works as described
Cons
  • It is relatively expensive compared to other types of battery isolator switches, which may not be worth the investment for some users

Product failed on my review.

I ordered the first unit, and it failed, so I returned it, and received a second unit. The second unit lasted for 6-8 starts, and then it failed.

Pros
  • Very nice. Same as the factory uses. Putting the same unit on two more trucks.
Cons
  • The installation process can be quite complicated, which may require professional assistance

Easy install and superior product

Awesome product! I installed this on my Jayco RV to prevent the batteries from being drained down while in storage. Super easy to install. Didn’t come with any instructions but I was able to easily pull them up online. (I could have thrown them away as well because I was excited to put in this new switch) anyone looking to install this on your RV let me know and I would be more than willing to share how I did it, how to install and where to install it. Super clan install and quality product…

Pros
  • Quality switch for a good price.
Cons
  • The switch is prone to failure over time, which may require costly repairs or replacements
