I've been struggling with the same problem. My sailboat & trailer weigh
about 1800 lbs. Chrysler says my mini-van can haul 2000 lbs but recommend
brakes for load over 1000 lbs.
When I went to the local trailer dealers, they almost laughed me off the
lot. One guy, who sells Venture trailers said all his customers try to
avoid brakes and will actually buy a smaller trailer than they need to avoid
brakes and the maintenance required. If you boat in salt water, get the
stainless steel discs.
