My reference to overkill was based on rigs size and capabilities vs terrain. At what point is it no longer technical and challenging.this also becomes a sliding scale as the progression happens.
1 might consider a 60 overkill to run 33's but not 37's.
take that to 40's where does the Dana 60 really sit? marginal, satisfactory but probably not overkill?
I don’t think a Dana 60 is silly for 35s if wheeled.
