thanks everyone,
I did go with the surge brakes Bought the coupler, drum/ hubs and backing plates locally A local NAPA shop can outfit us with 3/16 steel tubing and hoses to the brakes.
Electric just did not seem as effective on a double tow with the length of wire , loss of V/A that the truck might not supply. and the complexity.
Surge brake coupler and hyd. 10 " 2.25" dexter backing plates.
Surge brakes sized and adjusted properly are idiot proof, respond only to the weight of the load, independent of all other factors.
price wise very spendy ( hyd. backing pl. double, plus surge and hyd. lines and hoses) over electric by the time it is done. Even considering my time in my welding/ mech shop. . Cheap compared to the value of a life.
The drum brakes also have a free backing feature, so no need to lock out the coupler when backing the trailer. We are not in salt water so the more professional air/ elec/ over hyd. discs are over the top, nolicable for us.
I do make it a point to inspect pack and adjust regularly. My pappy tought me that down on the farm.
Thanks, I was headed this way just wanted a couple other opinions with experience. The electric system just had too many points to fail or not deliver braking power.
