The hitch on my Ram has a 3-4 inch rise, my truck to trailer is fairly level for towing.
I and others sometimes pitch the nose of the trailer down to help with opening the front shell, but I do that only when I'm on my own opening the camper.
I swapped to an electric tongue jack after a few years, and I agree with Bill, no rush. See how you use the trailer to see what needs changing or is fine for your usage.
I also echo Bill's comment to not force either shells. I ended up bending my folding faucet neck in half on one trip. Had to reach out to the OEM to get a replacement neck.
When closing, don't get distracted in your steps. I've had people come up to chat about the trailer and I have to think about where I stopped in closing. I'll do another walk around, so I didn't forget to close, move , disconnect or rearrange something inside to allow a safe close of a shell. Some folks have a checklist till they feel really comfy with the camper.
