BIlsteins all around. Very happy with them, van is much more stable in crosswinds and road undulations without a noticeable or significant ride degradation. Correct tire inflation is very important too.
Never saw any reason to put Bilstiens on, never did any rock climbing or a Baja 500's. Had handling issue with my 02 Roadtrek and out of desperation put the Bilsteins on. They did not fix the problem but made a noticeable difference.
