Brumby i had offroad was great because of the lower weight. I had a 91 model 4sp dual range - two motorbikes on the back doing some fairly nasty driving and it was fine and seemed to have better power and handling.
1800 Wagons - not too bad as well, although you notice the weight and its not as easy to manouvre as a brumby - but its a wagon, its expected.
Currently i have an L series and just took it off road for the first time on the weekend, i was impressed i followed my mate in a land cruiser and the only thing that stopped me was falling into a rut that meant my wheels where off the ground - stuck as.
The L series didnt seem to have as much power but it certainly felt ok driving and like others have said the ground clearance as standard is better than the brumby. Once i get a new water pump in the old L itll be back in the mud again
