Well doing landscaping for a living does not help towards having a clean truck!! I can haul anything from plants (in the cab and the bed), screenings, pavers, topsoil, mulch, weeds, brush in the back.
One advantage of owning lots of land is I can drive and dump some of the debris on the compost pile, brush pile to be chipped up pile or burn pile!! I also have spots to park the truck on an incline and hose out the truck bed. But the exterior can get a bit grimey!!
The inside gets cleaned/vaccuumed out fairly often when I am in season working.
Its not too bad now that I'm done and the only items we will be hauling is firewood from the farm or lumber.
The car is much cleaner-except if I use it to buy/transport plants-then I have to vaccuum-thank goodness for leather seats!!
