Got some Timbrens from jdboss. Took the camper out for a weekend trip, then took the truck out for a different trip without the camper.
With the camper:
First impression: Wish I could remove them right away, the ride is miserable.
After a while: The pendulum-like swaying did disappear, but the truck effectively has almost no rear suspension. It's like (it is?) riding on the bump stops. This is not the long term fix for us.
Without the camper: everything is okay most of the time, but any decent amount of bump (i.e. going over most bridges) was bad. The rear suspension would compress enough to engage them, and the effect is (unsurprisingly) jarring.
Related to this, I have this set of Timbrens to give away if anyone else wants them. Model DRTT3500E.
