I installed the 3611s on my Gen 2 with Deaver +3s. The "s" means it comes with a short 1" extension to allow the front to mount underneath the leaf springs. The arch of the Deaver +3s caused the rear eye hook to be raised up slightly. After talking to Roadmaster, they said the pressure of the spring would hold them in place.
When I cranked them down to the recommended 2 mm of spacing, the back of my truck was sitting 2" higher. It settled to only 1" higher, but it was very stiff compared to the Deavers. Since I was planning to remove them after picking up a load of furniture, I was fine with the temporary differences.
Unfortunately, after an initial test drive, I drive over a moderate sized bump on the road and the driver side spring assembly popped off of the rear eye hook. With a loud BANG, the assembly got wedged between my leaf springs and my rear shock plastic surround, so I had to drive home with it dangling under my truck as shown in the picture below. I was able to remove it by lifting the truck back up and lowering the axle down to its maximum height.

If you are not using the Deavers, they will work just fine. However, if you have Deavers or you are planning to add them in the future, you may want to consider another solution.
