Spread Axle do it yourself anybody considered it with ur reefer unit?

I don't see that there would be a problem. I installed a new Ambox 93( regular tandem box) on a 1999 Trailmobile trailer. I am certain you have already planned in your head how you go about lifting the trailer, rolling entire suspension out from underneath, etc. I would say if the holes line up w/pins on new box, then it should fit. One thing to consider is the kingpin measurement on this trailer. We had a spread custom built and the kingpin is @ 24 inches. Some folks choose less. This is so you don't end up heavy on the drives. Also, that is the suspension we have, it is just welded to the slider rails. Hope this helps. I'm certain I am missing a lot of other important details so hopefully more experienced folk post info.
