From the manufacturer
Flat towing, also referred to as “dinghy towing” or “four-down towing,” is a way of towing your car with all four wheels on the ground behind your RV. The tow vehicle is connected to the RV by a tow bar and follows you as you drive. When traveling in an RV, having a separate vehicle gives you the versatility and freedom to explore once you reach your destination.
The Blue Ox Patriot Brake is a versatile flat tow brake system for full-size SUVs, pickups, compact cars, hybrids, or multiple vehicles with different floorplan configurations. It provides real braking action with the same force as a foot on the brake pedal, in the middle of the pedal, at the same angle for true, responsive braking that is quicker and more responsive.
Protect your vehicle while towing behind your RV with the KarGard Protective Shield by Blue Ox. It is made from durable polyethylene and equipped with aluminum mounting equipment. The shield is designed for quick and easy installation and conveniently folds in half for storage. Towed vehicle shields guard against dirt, rocks, and other road debris your motorhome can kick up during travel.

This model is lighter than most and has many great features over my old Blue Ox
Reviewed in the United States on December 16, 2022The Ascent is about 8# lighter than my old Blue Ox that I purchased in 2014. The best feature is that the tow bars are non-binding, so very easy to unhook. This is the main reason I bought the new model, I got tired of trying to unhook the old style tow bars with binding arms. The old binding tow bars required that the tow be aligned dead straight with the motorhome and not on a downhill slope. Lord help you if you had to unhook on a curving road, it required 2 people, 1 to unhook and 1 to jockey the tow vehicle to release the tow bars. The docking is much easier also. I used the old model for over 125,000 miles to tow my Subaru to every state plus Alaska and it was nearly indestructible and is still usable. The Ascent appears to be much the same quality of construction, I expect it will last as long as I care to use it.

Good Product
Reviewed in the United States on August 14, 2025Easy to use and put on vehicles. Good quality. Glad I bought the Blue Ox. I also bought the vinyl cover for it when not in use.

Much lighter
Reviewed in the United States on June 29, 2023A lot better than my Alpha first gen. It's lighter and has non-binding latches. One thing surprising was the price swing. I first saw it on Amazon for $900 something and decided I didn't need it yet, so I waited to purchase. When I was ready to buy, the price shot up to $1200 something, which is about MSRP. I procrastinated until a week before my trip and luckily the price dropped to $900 again.

easy to hook up, easy to use.
Reviewed in the United States on October 12, 2024I'm using this, along with a different "hook to the bumper" device (I have a custom bumper, so I'm not buying and using the plate that they sell.) I've only taken my 2014 jeep 4 door wrangler out once with this setup and it was a test run, but everything seems well set up.

The lightweight aluminum model is worth the extra cost!
Reviewed in the United States on August 29, 2022I’ve owned 3 of these tow bars but this is the first aluminum model. MUCH easier to work with! One of the nicest things about Blue Ox is when you remove the bar and attachment posts from the car’s base plate, you can barely tell there is a tow bar attachment on the car. Other brands look pretty ugly with all the remaining hardware.
My only complaint was that the large bolts that allow the arms to swivel were so tight, I could barely move them. After slightly loosening them it is much better. Still a great product!

Great tow bar !
Reviewed in the United States on May 29, 2025Blue Ox makes a great tow bar, and we replaced our old one for same new version. Amazon price as well as product availability make this so easy.
