Most Popular Proportional System for Hyundai Tucson

I mounted this in a 2014 Chevy Spark. Finding a spot for the main control unit was interesting, but I found a video for a 2017 Spark that I could use. I did have to drill an extra hole in the mounting flange and car. I haven't taken it on a trip as of this time, but a tow around the block indicated it was working. One note, watch about placing the LED indicator behind the tinted part of the toad window. It makes it harder to see from the camper camera.

This braking system does what it's suppose to do, smooth proportional braking between motorhome air brakes and the tow vehicle. The only reason I did not rate at 5 stars is that there is a slight misalignment of air cylinder mounting bracket and 2022 Jeep Gladiator brake pedal.

The install on my Ford Maverick is clean and functional, so this is more of a customer service review... excellent customer service! During the 4-day towing set-up install, the forecast was for freezing temps and my rig was not winterized. I called in mid panic and the motorhome was moved indoors. A few months after using the tow set-up, a minor problem developed. I called and the CSR apologized and said, I can see how that might be frustrating, and a replacement cable (slightly longer) was sent free of charge.

Had a problem with the connection to the unit but called etrailer and they sent me a new one after sending the other back to them. The hole process very painless and the the staff at etrailer was great to work with. Thank you etrailer for your great response.

I am still scratching my head on the placement of the Main Unit. The floorboard area of the 2024 Jeep Wrangler is very small. The 2 levels of the rear of the unit are such that I can't seem to get the right height to stabilize the unit. The seat can be brought slightly forward but does not contact or even come close to the Handle when raised. With the plunger all the way in, there is hardly one half (1/4") inch of clearance before beginning to press the brake pedal. I can't find anyone else that has installed this unit. HELP please.
