I've been looking for years as well. Probably 15 yrs ago, I purchased from MacNutt's. It was a blended mix and the best soil I ever found. I tried them again 10 yrs later and it wasn't the same. Since then I've tried all the main suppliers Trio, Alpine and a few other landscape marts. All of their mixes look good at first, once the rain hits it, the supposed "compost" appears for what it really is...sticks, rocks, nothing broken down like it is supposed to be. Sorry to be of no help but post back if you find something.

I know you want a truckload but if you can settle for smaller amounts, I find the "Sunshine Mix" best of the bagged mixes.
