Replacing Trailer Bunks

[HarryO]

As a newbie to this forum I'm looking for feedback on my latest project. I have to replace the 2x6 bunks on my Venture single axle trailer. What's on there currently is marine carpeted painted 2x6 bunks fastened with galvanized lag screws. The lags are rusted and some of the bunks are warped so they have to go.

My plan is to buy top grade fir 2x6s. Paint them with gloss porch and deck enamel and then cap them with 1x4 composite boards in place of carpeting. I figured it is better to bolt them to the brackets with galvanized carriage bolts counter sunk slightly below the surface of the bunk boards and then cap each bunk with 1x4 composite/plastic boards centered on the 2x6 bunks and fastened with counter sunk stainless steel screws.

My questions are as follows:
1. Have any other members tried this method over standard marine carpet covered bunks?
2. Do any of you see any negatives or disadvantages to using this method?
3. Is there an advantage to having the toons sit on a dry surface rather than wet carpet?

I plan to leave my toon in the water for the season and store her covered on the trailer for the winter. Believe it or not the cost is roughly the same as carpeting the bunks and of course composite dosen't rot , rust or get torn.

All feed back is greatly appreciated and of course I plan to publish a thread showing this process with pics and costs. Thanks in advance for your replys.

Use galvanized carriage bolts to attach the 2x6's. You'll draw the bolt head into the wood as you tighten. I've had much better success with those as opposed to lag bolts. Never painted the lumber though.

crspang is spot on!

I only add that you counter sink the boards then insert the galvenized 5/16" carriage bolts to clear the head.
