I had mine for 10 years. It is picky about adjusting the cam arm length such that the detent on the cam is centered over the lobe. I have the same truck/trailer combo scary at 55mph and comfortable at 75mph depending on that adjustment.

Does it stay in adjustment?

If you optimize the WD setup on the truck, which sets the WD tension and then set the DC, then yes, the dual cam system stays in adjustment.

I am still running the same original cams I bought in 2003 which now have over 50,000 miles on them. I have changed campers and trucks which required me to change the sizing of the WD bars due to heavier tongue weights, but I am still using the original cams.

On my current camper and truck in my sig, I am using the 1,700# WD bars with my F350 truck bed full (500#) and the camper with a 1,600# tongue weight. From my experience, after optimizing the WD setup and dialing in the DC adjustment, I can vary the camper TW and or truck bed weight combo up to approx. +/- 150# and not have to make any WD or DC arm adjustments.

When I was running 1,200# WD bars on a 1,200# TW camper on my prior 2003 K2500 Suburban, I could adjust truck cargo and/or camper TW combo by approx. +/- 100# and not have to make any WD or DC setting.

In order for this to come out that way, you have to setup the WD and the DC cam arm adjustment optimized on your normal loaded truck and camper. Then you have some freedom to change bed to camper weights and still be OK.
