Get that trailer level, or barely nose down, friend. The config shown in the pic above makes for low tongue weight = propensity for trailer sway. At the least, that trailer will be moving around more than need be, calling for more steering corrections per 100-miles. Tire load is also off from FF to RR (braking).
And, from perspective around here, that flat plane of the trailer underside is like an airplane wing gaining lift. Towing rather comes down to tow vehicle rear axle traction, so a trailer moving side-to-side and light on its feet, so to speak, has not an attitude conducive to lane-centered stability.

I paid about $50 at a U-Haul store years ago. Uses a wrench to move up and down.
FWIW I don't ever trust the U-Haul management to have their techs make sure that:
tire pressure
lug nut torque
surge brake actuation
lighting
is fully operable and meeting spec according to their own guidelines. U-Haul specialzies in out-of-court settlements which do not disclose liability. Dumb renters, sure . . poorly-maintained equipment, bet on it. Their stuff is made well, but any of it can fall between the cracks.
Pleased you hit 20. Whats the percentage drop from solo, now? And over what terrain and distance? Any idea of total weight versus scale weight (payload)?
