In addition, the breakaway system will activate without any action by the driver. In your case, how will the solenoid by activated?
I will activate the solenoid with a standard breakaway switch.
The only question now... how long is the breakaway trip cable? Longer or shorter than the safety cables?
If the answer is "shorter", then the breakaway system would only have to slow the toad so it does not run into the back of the MH.
In that case the question of two-vs-four wheel breakaway brakes seems moot. IOW, rear-only brakes would be more than enough to slow the toad and avoid hitting the MH.
If the safety cables can dependably keep the toad from breaking
totally away, then I don't see the need for a breakaway system at all.
I have stopped trailers (twice) when they came off the hitch and were retained by the safety cables. Something to be avoided, but not a big deal either. In both cases, there was no damage.
UPDATE: The install instructions for the SMI system call for the breakaway cable being SHORTER than the safety cables. SO.. the breakaway is activated upon tow bar failure but while safety cables are still intact.
