But the design expects force applied upward from the suspension and tongue. That force increases and decreases, but the location does not change.
Nope!
The bad thing about gravity: it works everywhere.
The force is NOT induced just at the tongue and suspension. There is mass (force) induced into the frame at any point along the length of the house (as long as there is gravity).
Well sure gravity is a force on the whole unit. But the force I'm talking about is the equivalent of a 7000 lb hammer hitting upward where the suspension mounts. Depending on road speed and the height of bumps, that hammer may swing a short or longer stroke, but it always hits the same spot.
Years back I bought a 28 (IIRC) foot TT that had been parked in a barn for about 10 years. The 20 something that sold it told me "Dad always set it level, put the jacks down, so he could use to hide" I expected and found mouse damage. Planning to gut for office, so not a problem. What I did not expect was not a door or window worked right, including cabinet doors. Decided to build a flatbed. Removed all the appliances, cut house loose from frame, put straps on it to hold house down, took it to a landfill. Back to yard, started figuring what it would take to make that frame stiff enough. Pulled the axles, cut rest for scrap.
