    I have built well over a dozen trailers in the past 50 or so years and have used several spring lengths and sizes. I built two trailers using rear light truck springs, one a single axle and the other a tandem. Both trailers were built with smooth ride in mind. The single axle is a 6 x 16 enclosed trailer with outboard wheels and was built for moving equipment for sound re-enforcement. I just kept adding leaves to the springs ’til I got the ride I wanted and with shocks added it has surpassed my expectations for ride. Even empty it is exceptionally smooth. The 8 x 20 tandem was built as a mobile stage to be used at outdoor shows and also in parades where music cds were played. I set the axles quite close together which meant I had to overlap the springs without equalization. I accomplished this by turning the springs slightly on the axle mounts ’til the rear cleared the front springs. The rear axle has heavy duty shocks added to reduce sway and bounce. After 20 years of hauling all kinds of loads it has given absolutely no trouble and the looked for results were achieved. With the length of the springs and the built in clearance to the frame equalization has not been a factor. I’ve often wondered why all light duty trailer springs are built so short. With heavy trailers I can certainly see the advantage of the shorter springs.
