That's exactly what my 200tdi disco box was running, / now is running as far as wheels are concerned, absolutely no problems on any road or towing..If you run 7.50 x 16 / 235/85R16 and a Disco transfer box, then chances are it will be sluggish and over geared. You need quite a juiced up Tdi to make this work, else they are not great at all.
Ps I added lots of sound proofing to body and bonnet, it's quite quiet..
