With two models to choose from, we have the multi-axle trailer to fit your requirements. Big Bubba will handle most multi-axle needs. But if size really does matter, then turn to Bigger Bubba, the big-boned member of the Reitnouer family. All multi-axle trailers are available in three-, four-, seven-, and eight-axle configurations, as well as tri-nine and quad-nine designs. All combinations are available with various assortments of lift axles and steerable axles.
