Was another very nice day here, have been debating putting rollers on my boat trailer for more than a few years now, never seem to find the time so today I get up early. Hit the marine store before they even open, buy 4 sets of rollers slabs 6.5 inches wide by 5' long and return home. Build stands, jack up the boat, pull out the trailer and cut the old slides off before lunch time. Took all afternoon to weld in supports, adjust the roller slabs to the boat hull and then bolt everything in place. Boat moves very easy now, can`t ever forget to hook her in now before moving the trailer....LOL
