Have you tried using the sideway wood stacking strategy? It effectively multiplies the wood capacity by at least twice for trailers, and gets you wood stability in both downhill and uphill driving. (I think you already know this though)

Well, perhaps you're using the simple and fast method of just putting a few logs into the truck and trailer? The one I'm using is pretty time consuming compared to other strategies.
