M416
I am in the process of building, or having built, an off road chase trailer. I bought a new 3,500 lb. axle with 6 bolt hubs that will allow me to use Rally wheels on the trailer.
The axle is installed and I had them flip it, the springs and shocks are now bolted on top of the axle instead of underneath. It has raised the trailer a good 5". I wanted to use the same Rally wheels on the trailer as the truck so one spare could be used for both. When they tried to mount the Rally wheels the center hub would not fit over the hub guide on the housing. I had three Rally wheels lathed out for the trailer and spare.
The hitch is being extended two feet to allow a storage box in front of the cargo box of the trailer. It will hold 4, 5 gallon water cans. I chose to use a covered box because of mud issues.
Flipping the axle gives room underneath to allow mounting of the spare tire. I am running 33's so it will be good to get it out of the way and not eat up storage.
My adventures are on the open range of the High Plains in Western Kansas, actually the Smoky Hill river valley. If one was to use this trailer for rock crawling the axle flip may make it too top heavy. My main concern is driving over large areas of thick sage brush, yucca and cactis. Driving over this terrain is hell on wiring and trailer tires.
