With the stock axle
bounced so severely it literally unscrewed most of the interior trim screws, and cushions were tossed everywhere. The face of the furnace
fell off. I later changed out the axle
to a new Flexiride and switched to 14" wheels and tires
. The ride improved quite a bit. Much lower frequency oscillations now. Properly matched shocks would certainly improve the ride even further. Trailers without shocks will usually have tires
worn with cupping patterns caused by the constant hopping at the rigs resonant frequency. Our Jeep Wrangler tug has worn out shocks and the ride is suffering badly. Ka-ching! It's only money..
