My advice, tandem (dual axles, 4 tires) surge brakes break away tongue. I have a nice trailer but it's a single axle trailer with surge brakes but doesnt have break away tongue.
Have the the bunks set up so as you have 4 total so it creates a cradle, 2 closer together to support the keel and 2 shorter ones spread further apart.
I'm sure others will have opinions. And if your in salt an aluminum would be the way to go.
