Dual wheels on the rear axles might be good at increasing payload and distributing weight but when it comes to soft terrain they become expensive trench digging shovels. I came across this International with a massive tree spade out back at the local tire shop the other day. Large rear flotation tires not only help this truck navigate the job site but help to minimize damage to tree roots.
This Freightliner Cascadia has similar set of rubber out back. This truck hauls for a local dairy farm and the tow hooks up front suggest this truck needs a little help moving through the fields every now and then.
