On my 29M, doing the CHF, aligning the front end and setting the tire pressures helped with the handling. The saf t plus steering stabilizer is a safety enhancement that may help in the event of a front tire blow out. The sumo springs I added to the front end were the last change I made and they were the improvement that benefited me the most. I can drive the rig now with no issues from passing trucks and mega buses. The rides is also a tad smoother.
