Roller jacks.....

I bought a 1-1/4 ton Walker floor jack in '77. Had to rebuild the cylinder once so far.

When I trailer the boat I bring an aluminum Alltrade(?) floor jack I got on clearance from Wal Mart for 35 bucks on clearance. It's worked well and is much more travel worthy than the heavy Walker. I should have bought all four they had for that price but I had no clue if they were any good at the time.
