After 4 trips to Baja and numerous off-road adventures, I feel like my +3SD Deavers are sagging. Has anyone had their Deavers re-arched. If so, were you pleased with the results and how much did it cost? Trying to decide on this route or going with Deavers +3HD. I carry a second spare, a jack and a large box that probably adds 300 lbs to the back. Not Otto mention 12v coolers and battery pack in the cab.
