I had to deal with driving snow and 20 mph and higher wind and so was glad to have had the dealer install the heavy duty version of the SumoSprings front and rear.
Shocks can provide resistance in turns but they do not add load capacity and that is what is needed in a turn or with a cross wind as this shifts weight from one side of the vehicle to the other side which then has to carry more than 50% of the weight.
In my own experience the best way to improve the handling has been to add leaf springs to provide more support. No different than what truck manufacturers do with the use of leaf springs instead of coil springs on their heavy duty models and with the 1-ton having an extra set of springs as compared to the 3/4 ton or 2500 models.
The problem with relying on shocks is that they are not designed for load support, other than the air shock versions, and so they will work harder and wear out much sooner as a result.
SumoSprings do not so much add more payload capacity as they reduce the distance for the suspension bottoming out and so minimize sway on the road. Last I checked the SumoSprings only had a 2-year warranty and so they too are a temporary fix, although one that requires very little labor to install.

I measured the sway bar on my 2020 View and it is 1 3/8". The Hellwig is 1 1/2". That 1/8" must make a big difference base on posts here.
