You are doing the right thing.
The MorRyde will help with fore/aft movement.
I have a BD3 hitch and it really, really cushions the forces between an otherwise rigid truck/trailer connection.
The money your are spending is probably less than the possible repairs needed in the future to repair the pin box area due to the harsh impact if you continue to use your current set-up.
I'm amazed how many people don't even consider an air hitch for their truck when people on the forums ask for hitch recommendations. The difference is amazing in the noise and banging of the impact when on these harsh roads. Its great to look in the review mirror and see the pin box floating on the air hitch and not to have all the impact you are speaking of.
I have the BD3 with a GM/Ford puck adapter. When I bought the BD3 the 5 was not on the market yet and there was no puck adapter. Then they came out with one. I'd love to sell the combo and get the BD5 that requires no adapter. I'm right at the max on the BD3 so the 5 would be a nice upgrade.
Let us know the difference you experience when you get the upgrades installed and tested. You will love it! Safe travels.
