Moving... easiest/most cost effective way to ship trailer?

It could be a 42 ft gooseneck with a kingpin put in it. But there's the weight issue, and if it's got electric brakes, the unit pulling it will have to have an electric brake controller on it.

 

Need a little more info on the trailer, but my company Trailer Transit Porter IN 219-926-2111 might be able to handle it. If it is loaded, it has to be registered/inspected. We can't put transport plates on a loaded trailer. We can handle Electric brakes/pintle hook/ball hitch etc. It has to be roadable. If our driver gets there, especially in an out of the way place like Montana and it is not roadworthy, they would be charged for the bobtail and trip order not used.
Give the sales people a call.
