05 1500 express front spring preference?
 

I just bought an 05 1500 express high top conversion. I've previously owned an 00 1500 standard conversion. This 05 seems to ride like a marshmellow and is all over the road in the wind.
So I have went about; buying new tires(michelin) new kyb has matic shocks(bilstein were not available for this year and would have been my preference) had an alignment done, rear sway bar, and new polyurathane on the front away bar.
The rear bar tightened it up a bit but now I am really aware that the front is soft. I want to buy springs that can hold the weight of this high top but don't send me over the edge and make it ride like a 3500. Any suggestions?

2500 springs the same?

2500 is torsion axle. Anybody? Mine is rwd

my 2002 express 2500 has coils up front. I though torsion bars were only used on AWD models.
