2020 Subaru Outback Onyx Edition XT
i thought all the u-haul trailers have surge brakes. Certainly the last one I rented did. The Surge brakes use hydraulic fluid to activate the brakes when the tongue is compressed. I think maybe the smallest u-haul trailer doesn’t have brakes. Actually, by law, in most states, the larger u-haul trailers are required to have brakes. Not electric brakes, just brakes. Since U-Haul cannot rely on people having brake controllers, they are forced into putting surge brakes on their trailers.What's the argument? The car with more torque and the beefier CVT can tow 800 pounds more "if the trailer has brakes".
Outbacks in Europe have much higher tow ratings. People tow trailers there instead of owning monster pickup trucks so the market demands higher tow ratings. Same car, different ratings. The North American specs are extremely conservative. An empty U Haul weighs 900 pounds and doesn't have brakes. People tow a modest load with those on Outbacks all the time.
