The LM146 is a general-purpose flatbed aimed at landscaping, construction and plumbing trades that need a long, wide load bed with a high payload on a single 3500kg-braked chassis. It is used where loads are bulky or awkwardly shaped rather than plant machinery, which typically goes on the ramped GX range instead.
