ESCAPE ARTIST!
I love these handles some of you have come up with... yesterday I read a post from someone calling them self Texescapee/
Getting into the Escape scene too late to get a good handle.
I really tried to measure bounce in my Casita scientifically.
I had an accelerometer but it broke.
I tied a plum bob to the AC and filmed it but could not discern anything.
Finally I got an old shop indicator and took out the spring and packed it full of grease and fixed it to the frame to measure the dog bone movement on the axle.
Drove it over a two by four at different speeds, different tire pressures, and with/without shocks attached.
All I am (somehat) convinced of is the flatter tires roll over things easier and the shocks are good for tough hits like a pot hole.
That's all.

Mythbusters had an episode where they confirmed that a car (big Buick) ran smoother over washboard roads at 40mph that it did at 20mph.
I know that I can do that with my truck too although the rigid rear axle sometimes launches me into an uncontrollable side slip... especially on curves.
But I will not do that ever with my Casita because I cant be sure that the trailer tires are in sync with the truck tires and no need in popping more rivets than necessary
But back to the original question:
I was watching one tandem axle trailer move over a rough rocky road faster than anyone else and it "appeared" that the two axles shared a bump. Floating over it.
Not sure.
