IMO, surge (hydraulic) brakes are good for any application. If set up correctly, they virtually eliminate extra braking on the pull vehicle. My yukon was almost 'pushed' thru and intersection on Hwy 65 by the boat/trailer I was towing due to surge brakes out of adjustment.
Then, towing our pontoon, 24ft, dual axle bunk trailer, I could feel the surge brakes actually pull the yukon to a stop.
Remember, even tho mfg'ers do not put brakes on ALL axles, that is the MN statute for towing with brakes. You most likely won't get stopped for that infraction, but, if in an accident, that will come up.
