Do any of you have the conversion kit for the pick up beds to make it a dump bed? I've seen the conversion kits on sale in the northern tool magazines. It sounds like a real great idea. Costs about 1,000.00. It would make unloading easier and basically eliminate the need for a dump trailer. (for my needs at least) Are there any downsides in having one of these? It will be used on a 2500hd 8 foot bed chevy.
