To everyone following this thread, I didn't notice any mension of the possible
legal tbl if you have an accident, maybe someone injured or killed and some
lawyer discovers that you didn't have trailer brakes even though the minivan
builder recommended them............$$$$$$$$$, and possibly your insurance
company will refuse to pay as a result of you not following that
recommendation!
Also some boat builders (BOSTON WHALER?) recommend against rollers on trailers.
Best wisher
