Cabover/truck Struts
Hey all......does anyone use the Lance (or other make)cabover/truck struts? Are they needed or is it just extra insurance against bouncing? Bruce

Lots of controversy on that subject. I encourage you to do a search on RV.NET for hours of reading.
Are they needed? How many TCs do you see with them? How many TCs come with them from the manufacture? How many companies manufacture them?
From all I have read, some truck/TC combinations on some roads have issues with porpoising. The cement highways usually are the worse. Long story as to why. Usually this is an indicator of the need for stronger shocks.
The truck frame flexes between the cab and the bed. Lots of stress there. It should be expected the cab over will move independently from the cab. When you install the struts, they are absorbing lots of this stress. If the struts are connected at the cowl of the truck, and on the end of the cab over, does it not make sense that those two areas now have that stress. Is your TC designed to stand this stress? You might ask the manufacture of your TC. I have seen damage on the mounting points of the struts, usually on the TC. I also question the added stress on the overhead framing of the TC.
From what I have read soft suspension (including soft shocks), on cement roads at certain speeds make the truck/TC the most vulnerable to porpoising. I personally would not use struts. I would look for solutions to the porpoising, including heavier shocks, increasing or decreasing my speed on that stretch of highway.
