Boat and Box trailers use simple suspension systems in single-axle and tandem-axle configurations.

However, tandem axle suspension does not load share, so the spring must be 20% larger in load sharing.
Why?
Axle loadings for slipper suspension are limited to 120% of full load.

For example, with one wheel on the gutter, the other does not touch the ground. As a result, tandem axles do not share the load.
