The Reese unit went in the back pucks easily. The left front was a little tighter but the right front got just past the surface and wouldn't go any further. I could probably have forced it but wondered would I be able to get out. I called the business where it was ordered from but they were closed for Good Friday. If they tell me to persuade it forcefully I will. Also waiting for info from Corporate Chrysler as to the configuration of the pucks. They were closed Good Friday as well. My truck was the first the dealer I purchased it from that had this new tow package so they couldn't tell me the puck configuration either.
Your pictures did not upload, so I can't tell what it is that you mean by relief. What I remember (it was six months ago) from my install, was that the release/arms had to be in just the right positions so all four were going in the exact same direction. We then carefully positioned all four corners above the holes in the bed. Even then, the back two dropped right in, so we pushed back and down on the front two - there were boots involved - which got them started into the holes. At that point we applied the "appropriate" down force with said boots and in they went......
If it makes you feel any better, my RAM dealer was useless as well - they didn't even know that the adapter was required in order to install a fifth wheel hitch
That's all I got, my friend, hope it helps
