If I get a Hunter 216, I plan to get surge brakes put on the trailer. Does anyone know whether disk or drum brakes would apply better for the 216 trailer? Also, does anyone know what price one would expect to pay to get the trailer retrofitted with surge brakes? I assume any RV trailer shop could do it... I was told by some Hunter rep that one might be able to special order a trailer (if buying new) with surge brakes for around $600 more. But surge brakes are not yet an official option for the 216....
