I shifted a van from Mount Isa to Mackay about 15 years ago. Wasn't a big van, an 18 or 20 footer, and I had an old EB Falcon to tow it with. It had a lot of stuff in it. Every little nook and cranny had something in it, I'd been living in it for a few years, as you kind of do in Mount Isa.

Got about 40ks out of town and after the third time I had to hit the electric brakes to straighten things up, I pulled off the road. I took everything out of the top cupboards and put it on the floor, and shifted a lot of stuff that was at the back of the van (like the heavy annexe canvas) right to the front of the van.

That turned a 80kmhr pushy swaying nightmare into a 100kmhr easy tow.
