Are the helper springs only engaged when the RV is fully loaded or engaged all of the time?
So, the under steer. I have driven some fast cars and I really only get under steer when really jamming into a turn at high speed and the front wheels slide a little and I really don't drive the Interstate that fast so I could not comment too much on that.
As for the helper springs, while we are at rest, the spring are resting right against the OEMs with some rubber bushings in between. It lifts the rig by 2 springs which by the bumper adds up to about 2-3 inches. The end so the helper springs have a rubber spacer at each end about 1" high which touches the original leaf springs. While at rest, they are not loaded too much but are definitely touching and keeping the rig slightly raised.
One thing is that I can drive over a speed bump at 10-20mph and it handles like a car and the leaf springs really just lift the rig up over the bump and not just bounce through it. We also have a hitch mounted Vespa at 250lbs on and EXT version so we have some pretty hefty back end weight.
Hopes is helps.
