I'm very new to all of this and don't know much but my guess is that your Breakaway Switch or wiring is bad. The breakaway might possibly be connected to only one axle by design??? ... or the connection to that axle is faulty???


For the chocks, I've just been using 2 on the right and 2 on the left in between the tandems. I don't see why any more would be necessary.


For loading your bikes, I can only speak from experience as a former truck driver that I would park them all close to the walls to keep your load over the wheels. Think of it as a catamaran sail boat where you want weight as far out as possible to hold that side down while turning on road curves or initiating an emergency swurve to dodge an idiot on the road.
