Maybe you had better luck than I but my Trojans seem did not to like shaking. The two installed on my sailboat gave far less than expected life, despite being charged daily via regulated solar panels. The water level also required constant checking.
I now use maintenance free Delco 31's. The best service life I got was from AC Delco Voyager batteries, still working after 6 years service. Unfortunately these are no longer available I believe.

Trojans have been the benchmark in deep cycle storage & are highly regaurded by solar companies & RV installers. I've certainly had an excellent run with mine. Yes they do require occational checking of the electrolite level as if the plates are exposed for any length of time would lead to premature failure.
With the angles a sailboat gets on it wouldn't surprise me yours had a short life. I would have thought a sealed AGM or Gel battery would have been a better choice for your particular application.
