When comparing tyres, watch out for load ratings as a 4 wheel 4000kg will require high ratings. The standard for this size tyre is 108, which is not enough for 4000kg. If it is dual rear wheel or tag axle, you'll likely not need high load ratings and the front axle will be the limiting factor. Make sure you check your maximum axle loadings against a tyre load rating table.
Rather than van tyres, you can use tyres intended for heavy 4WD vehicles. They tend to be a bit noisy compared to pure road tyres and not as fuel efficient, but they will be pretty good off-road and still acceptable on motorways if you're not intending to seriously break the speed limits. I see that you mention the front wheels digging in, so you probably have either 4 wheel FWD, or a FWD tag axle. In both cases, your traction will not be as good as a DRW, where about 70% of the weight is over driven wheels. Instead, you'll have more like 35-45%. But that just means you need all the help you can get, right?
When I had my old DRW Winnebago, I fitted Toyo Open Country All Terrain, which were a great compromise between motorway miles and muddy fields. Be careful, though, as the standard load rating for these tyres is 104. Unless you have DRW or tag axle, you'll need the 115/112 version, which is harder to find and more expensive. You could also try the BF Goodrich 225/75R16/115 T/A KO2.
Both of these tyres have "Mud Terrain" versions in this size as well. They will be pretty miserable on road, but excellent on mud. They'd also stand out and be talking points!
