I was taught that the trailer should stop itself and the truck should stop itself. You should feel little to no difference between stopping an empty truck and stopping while towing. This being with electric brakes. Surge brakes are a whole 'nother story. YMMV...
Lyle, I agree, and would’nt want the trailer to try to “remove” th hitch from the truck bed.....just a little tug!
Surge brakes.....yes another story! They only work if the tow vehicle is actually “trying” to stop the combination. If it’s slick enough... the surge brake “may not” be activated. I have “surge brakes” on our boat trailer....but not likely to be “ice fishing” with the boat! :B More of my “paranoia” surfacing! ;)
