Thread Title: Planning an Alaska haul with C28 – Is a Tri-Axle 5200lb with EOH necessary?
Post Body:
Hey everyone,
I’m looking into a custom aluminum trailer build for a Cutwater 28 to handle a long-haul trip up to Alaska. I wanted to get the group's consensus on the axle and brake setup before locking it in.

The current build spec sheet I'm looking at features a tri-axle frame with three 5,200 lb torsion axles.
  1. For those of you who have scaled your C28 on the road, does a 15,600 lb total capacity feel like the right safety margin once fully loaded with fuel, water, and gear? [1, 2]
  2. The trailer currently comes standard with regular electric brakes. Some folks have strongly advised me that standard electric brakes will fail instantly from launch submersion and that I need to upgrade to Electric-Over-Hydraulic (EOH) disc brakes—especially for mountain passes. For an AlCan trip, is the EOH upgrade mandatory?
  3. Given the stepped hull and the keel pocket on the C28, what specific target bunk measurements or setups should I make sure the trailer builder implements so it sits right? [1, 2]
Would love to hear from anyone who trailers their 28 long distances or has taken their rig up north.
Thanks in advance!
