I've found a few threads on this searching, but I'd like to hash out some details. I don't want to debate the single vs tandem axle issues, but rather what to use for the dually axle.

I'm really looking at the scorpion hauler type trailer. They are still making them, but I haven't gotten a cost yet. I can't find anything on their website any more, but I'm attaching a couple pics other's have posted here.

What would be a good axle donor? Something like a 14-bolt dually out of a truck/van? How much does one of these axles weigh? What's it's track width? And what would be a reasonable weight limit it could carry?

I was also thinking about a surplus generator trailer. Some of those use a single dually axle and there would be no differential to deal with.

I know brakes are gonna be an issue. A 14 bolt could be hooked to a surge brake controller, or use a high $$ elec/hydro controller. The military axles are usually air over hydro I think.

Any other suggestions? Ideas? Concerns? Donors? I'm looking to carry ~4500 lbs on a 95" - 105" wheelbase. No ramps and driving up over the trailer wheels to sit in wheel pockets.

If you want duals for a single axle trailer the lightest trailer axle I can think of set up for duals is 9K.

Another option would be a 7K trailer axle with a set of duals on it. I would check with a few vendors to see if the spindles/bearings were up to the load of dual tires though.

Surge brakes suck,I would avoid them at all cost. A 9K trailer axle might be cheaper than setting up a electric/hydro actuactor.

Weight distribution will be interesting on this type of trailer! :D

I would look into this. I hate the surge brakes on the boat trailer's I've pulled.
