Question:
Building a offroad trailer that is lightweight. I need a 5x5 pattern for my wheels and electric brakes. I think a 3500lb axle is overkill as the trailer will be under 2000lb. So Is there a 7 brake hum with 5x5 or is there a way to put 10 hubs on the 2200lb axle? Trying to avoid a stiff ride on a light trailer offroad. Possible I could do a 3500lb axle with lighter springs?

Hey Kevin,
Since you're planning on taking the trailer off road I recommend not going with an axle and instead building the trailer with the Timbren Axle-Less Trailer Suspension # ASR1THDS02. This is rated for 2,200lbs but uses a 3,500lb spindle so you'd be able to use larger tires and put 10" hubs on. They have built-in Timbren jounce springs to handle the rough terrain and work independently for a less bouncy ride. Without an axle beam in the way you'll have better ground clearance a well.
For the brakes you can use the etrailer Electric Trailer Brakes # AKEBRK-35 or # AKEBRK-35-SA if you want self-adjusting brakes. For the hubs/drums the Easy Grease Trailer Hub and Drum Assembly # AKHD-550-35-EZ-K would be a great option and comes with the bearings pre-greased so you'll just need to lube up the spindle and slip the hubs on.
If you went with a standard leaf spring suspension/axle you would have to size up to 3,500lbs in order to get a compatible 5 on 5 bolt pattern hub.

The Tumbren is exactly whatbI had on the last trailer. It was nice but stiff, and the rubber inserts broke in a couple years and they wanted another $300 for the replacements. I never found myself needing the clearance. They were also a little more involved in setting up. I want to keep this trailer simple. I will do a 3500lb axle and probably do the 2000lb leafs.
