Without debating whether patches are better than plugs, or how an improperly inserted one can cause damage to the belts of the tire, it is worth considering whether carrying the larger items, as you mentioned, increases the likelihood of a failure. If it is a rather light van and the loads aren't too heavy, then the risks are less that if if were a larger conversion van and you were hauling items like steel to a scrapyard.
