I'm not sure about tag axles though, if they lift or lower the pressure I guess they're OK and the extra capacity is nice in case you carry your rock collection along.
Well when I had a 38 foot Gulfstream DP with a single rear axle I felt like it was top heavy and ready to roll on exits and sharp turns
with moderate winds I felt like I was being pushed off of the road
when trucks passed I DID THE SHIMMY
With tag axles I never feel top heavy
I never do the shimmy as trucks pass
and in high winds ------ I feel comfortable , but the comfort drive may be the reason for that-- I am not sure ?
