The only trailers i have seen with surge brakes are U=haul, very few boats, and someone tried it on some of the trailers at work, an electric company i worked for. I am a retired electric lineman.
They arent very nice to back up with,, loaded very bad, they drag/brake. Towing a trailer with said surge brakes in the winter with snow and or ice on the road. Not good. I have done it plenty with bucket trucks/utility trucks.
Surge brake trailers, i havent seen any with the break away braking, or they would just be electric brakes.
My Curt hitch isnt any lower than other stuff under the car, if anything, higher. I will/would take the beefy hitch hitting instead of ripping off the plastic bumper held on by push pins, any day.
Giving the suby some credit. They,, at least have the setup for the 4 prong plug and are set up to,,, install a hitch. OEM or choice of aftermarket. Perfect for those that might not tow, but use a rear rack and or bikes on the back, that can opt for adding lights blocked by shhtuff on the rack or the bikes.
I have had vehicles that could tow lots more, with no plug and play light set up.
Now,, i leave it to those that ( will ) be towing with,,, brakes to look up the info for the blue tooth brake controller, and what kind of power, said trailer brakes may need. Thennnnn, look up what power is available fused with the wire already run, to plug and play into the rear lighter socket for brake power.
For $25, a person can make a 4 to 7 plug and bounce of the lighter plug at the back to use a blue tooth brake controller with plenty of power to run brakes. NOW, running the camper fridge and charging lithium batts on the camper, not so much. Brakes only, just fine.
Point proven, the trailers at work, double axel all wheels very heavy brakes. Rated for very heavy stuff. All backed up with a cheep solar charger, on the trailer batt, that was a same thing used in a lawn mower.
