Bringing in for warranty but asking around also.

Van is only 8000km new. Van vibrates at around 80km/h, or at least that's when I can feel it. The vibration gets worse as speed increases.

Only thing out of the ordinary was me towing a 800lb tin boat yesterday for 60km at about 80km/hr.

any ideas? Thinking I am glad I opted for the upgraded warranty.

 

It's possible you threw off a wheel weight. If that's the case it should be a relatively easy fix.

 

Sounds like a wheel out of balance or a tire is separating.
Also do you notice the vibration more on the steering wheel or the seat.
This will help find where the trouble is.
