Nope. Works like a charm. The only time I had an issue was when I needed to winch myself out of a mud hole... I disconnected the power steering and gained quite a bit. Other than that, no problem. I have 2x 40W light bar, power steering, hardwired USB charger and.... a rear view camera!!! Yes I know!!!! but with the huge box I built for the back Rack, I needed something. What I also added is a 2 gauge cable conected to the battery with a winch connector in my box. I made attachments for that like boaster cable so I can boost someone or get boost myself and I can also temporarely connect a second battery If I need to winch myself out again. I also made an attatchment with a 12 volts socket to put a 12 volts cooler or any other 12 volt accessories in my box.
