Yea autolevel just gets you that last little bit but never let it lift the tires. If necessary, back the low side tires onto some blocking to get it close to level and then let auto level do the rest. It can bend the frame and/or bend the leveling jacks.
The lube plates are fantastic. They get rid of the necessity to grease the hitch.
Those fifth wheel tripods don't really do a whole lot in my opinion but some people swear by them. I tried one once and sold it. I noticed that it didn't really do much for me other than add a tripping hazard when I needed to get to my under nose storage in the dark.
The best thing that I found to stabilize our camper that didn't have auto level were JT Strongarms. They made the rig rock solid. The very last one we sold had 6 point auto level and I learned that if I blocked under the leveling jacks to limit their extension the trailer was much more solid. The shorter the jacks, the tighter it felt. I ended up not needing stabilizers on that one.
One more thing.... tires play a part as well. On the one we had with no auto level, we had the stock el cheapo tires on them and they have a lot of bounce to them. The last one I installed Sailun G rated tires on and they had no give. That helped a lot too. When I took off the stock tires you could literally fold them in half.
