Hi TucsonWJ 5x8 Off-road CT,
As you probably already know ... but I thought I would add my $.02
As you realize by your comments on your axle flip ... Most trailer axles are designed with a “bend” in the tube that will deflect when the load (weight of the trailer) is applied. An interesting point is that a trailer that runs long distances without a load may be better without axle camber. In thinking about this, a heavy duty straight axle may work in your build, if the overall/gross trailer weight is low. take a look below:
http://blog.easternmarine.com/trailer-axle-camber-what-its-all-about/When I did my build, I changed the axle from a 4" drop to an under slung straight axle. I kept the same 3500 lb. rating and camber as the trailer was to be used double-duty (cargo & off-road) ... it has worked great so far and has over 6,000 miles of close to rated load or maybe even slightly more without issues. It also has a number of prospecting trips into the Bradshaws and Black Canyon mountains north of Phoenix and quite a few trips into the rough mountains north of Arivaca, south of Tucson. I have been happy with the build and the trailer now lives in Minnesota where it will travel to Montana, Idaho, South Dakota, and of course, make annual prospecting trips to Washington, Oregon, California and the Southwest ... and anywhere else my mood takes me, but lots & lots of miles
The end use of the axle should play a role on the camber desired, e.g., if the load remains low, but the terrain is rough, strength may be the determining factor and not a lot of camber ... anyway, just my thoughts
Good luck on your build
