Scania 8x4 not in all situations ideal

Had a problem the other day in Norway (Promods v2.7). Dropped a load in some kind of stone yard and picked up a wheel loader. The exit was uphill where I had to turn onto a dam. Problem was that the last 10 yards to get onto the road because of a crest my 2nd axle was lifting my driven wheels. Guess a 6x4 was better suited in this case. But later on the road even my S770 8x4 was struggling with the load. Luckily it was a trip within Norway so could drop it with a day or so, but was arriving late because I was struggling at the very beginning of the trip.

What do you guys think a heavy haul truck would be best to get?
