bus - the GV is awesome. Most of the time I can stay in 2 wheel drive where others are in 4 lo. I just give it a bit of gas and she lights up throwing mud / rocks whatever for miles
. When you drop it into 4 lo there is plenty of power to take care of most things. I have not fitted my 5.1 r&p's yet either - it is still running stock 4.3's
It is a deffinite step up from the 2.0 V6 - quite, comfortable on long journeys, stacks more power, deffinitely more refined - however, I like my gen1 2.0 V6 because the suspension is a better design ( read - more flex ) and it has similar characteristics power wise to the GV, just less of it - 2.0 V6 135 hp , 2.5 V6 165 hp. Not much but it all helps
I like them both for different reasons - GV is my family adventure rig - 2.0 V6 is my club rig and is the one that takes the knocks
