I have always heard that you should never leave salt in a spreader overnight outside because it will freexe solid.<p>I have been toying with the idea of a V-box for next season(tired of fooling with bags). The problem that is plaguing me is that I have know way of storing or loading salt at my location. I would have to rely on local suppliers for the salt. Since I usually have to go out very early in the morning(3am) the supply yards will be closed. This would force me to get loaded the day before a storm is predicted. I would have to be loaded before the supply yard closes, 5pm. This would mean that the salt would be sitting out in the hopper for about 12 hours. Is this going to cause a problem?<p>Another problem that I have is that if I get loaded beforehand, and the weather forecast is worng, what do I do with the hopper full of salt?<p>I have toyed with the idea of using some kind of heater in the hopper to keep it from freezing. I was thinking of something along the lines of the tape that you install in the gutters of your house to keep them from freezing. I could plug it in while the truck is sitting, but would that be enough to keep the salt from freezing?<p>Another idea I had was kinda unrealistic, but warrants some thought. Something along the lines of a heated bed like the asphalt trucks use to keep the asphalt soft during transport. The trucks exhaust travels through the floor and sides of the bed, and heats the bed. Now, that is really not practical for this application.<p>So what do you guys do that use V boxes? Do you depend on your supplier? Load your own? Something different? <p>PS If I had the means to load the material my self, I would have no question of what to do, but lacking a loader, I am a bit troubled.
