So I'm new to the camping in truck bed under my shell and have a question about storing cooler and other smell items while we are sleeping. At campgrounds with bear boxes we will use those but my question is mainly for areas along the 395, Sierra, that are dispersed camping. Should we keep the cooler, food box, etc in the truck bed with us or the cab or do as I do when backpacking and store a little ways away? Thanks for the input.
