is there anything i can use in the bed of the truck to hold the bags in place so they don't slide around?

 

I've seen people take some 2x4's and nail them together into an I shape to keep the sandbags from sliding. Basically, cut 2 2x4's to length to fit width wise across the bed on either side of the humps, then cut one or two more 2x4's and attach to the first pieces. Put the sandbags in between and you are done.

MUCH better than using bags

 

i carry a shovel and when i get to the mountains, i shovel snow and put in the bed, here the snow is wet and heavy, never had any problems
