Jim,
if you use tripod, strong arms, or most anything else you will lose the slosh! So if that is a source of entertainment of you....don't do anything! Sorry could not resist!
one other thing I did was purchase 4 scissor jacks and after a few trial and errors located them permanently on the frame just in front of the wheels and about half way back from wheel to the end of the rig. Once I found the sweet spots I bolted them to the frame. They help too.
Use a drill and tighten with wrench.
Since we we move a lot many times I don't put the tripod out. We are at our last sales calls on this six week trip. I am waiting for linda right now seeing her last customer here in Auburn, AL. Since laundry will wait until we get home on Friday I did not put the tripod up.
