Although it is theoretically possible to use a DPDT Relay (in place of the two 5-pin Relays), there are no socket bases with sufficient current-handling capability (up to 30A on 12V "power" wires). When the switch is off (as shown), the Trailer "Battery Charge wire" runs at 12V, up to 30A. When the switch is on and the 5-pin Relays are switched, up to 24A goes into the "12V input" side of the booster, and the output/Bargman wires carry no more than 12A.
