Coach jerking at low speed

[Fogbelly]

I bought a new Precept 31UL....only a 3200 miles now. The coach jerks slightly but noticibly at very low speeds .... seems a bit worse when turning.

It is very smooth as soon as I am moving faster than walking speed and highway speed.

Turning the traction control off has no effect.

ABS? Torque converter? Emergency brake?

I hate to answer a question with a question, but...

Does it do it in neutral and rolling or only when the engine and transmission is engaged?

I assume no idle vibrations when sitting still?

Straight as well as turning?

Possibly a warped brake disk?

I wouldn't be overly concerned until you have a few thousand miles on it, or if it gets worse. I would however suggest checking the transmission fluid level if your has a dipstick to do so. ~CA
