END DUMP MINIMUM REQUIREMENTS
What are the MINIMUM requirements that an end dump needs to be in order to haul, let's say a full load of Fertlizer? I've got a 30 footer but the sides aren't tall enough to haul most loads other than sand and gravel... I have no problem hauling sand and gravel but would like to possibly upgrade my trailer to haul some of the loads that I see posted on here. I need to know the length of the trailer and the height of the sides... I also see that it's good to have the coal door as well......
