My buddy's ramlin trailer for his nautique has lag bolts. It definitely makes it easier to install new ones at the ramp, but if you are have a couple of hours to spare, you might as well use through bolts. Lags bolts will probably hold up fine, but the marginal additional effort required to through bolt them was worth it to me.
