The jack will work fine for your trailer. The only issue with the LCI units is reliability. I am on my 3rd season with my LCI jack and its still working fine (knock wood). I cover mine though when not in use so that rain and dirt don't work its way into it. I think that's a contributor to the early failure rate on these jacks. I read on one of the forums where someone took theirs apart and found it pretty corroded inside.
I will replace mine with a Husky or Barker when it finally does bite the dust.
Oh ya another thing to help on all jacks is to make sure you chock the wheels BEFORE you raise/lower the jack that way there is less stress on the post from fwd/bkwd rolling when setting up.
