Rockwood suspension

Being in the same boat, so to speak, I contacted Dexter and had several conversations with one of the techs. They used to offer a kit for raising the trailer, but no longer recommend it. He didn't say why, but I assume maybe problems with side loading issues and strength of bracket on axle. Also you can't weld axle to beef up bracket because of the torsion rubber inside. He recommended new axles with more down angle on the wheel stubs to raise the trailer. I looked at the axles and think there's probably a way to raise them with some proper engineering and fabrication. I just don't want to burn my warranty. My clearance is a little over 5 inches and my rear axle weight is getting close to max, so will keep an eye on everything. I was hoping the stupid truck would squat more, so will just load the trailer accordingly.
