Everything came in as advertised. Purchased CE Smith bolsters, u-brackets, lag screws and carpet. Added two bunk boards to my Lowe trailer (Karavan). Only had two boards and I wanted extra to support the weight of the boat. Everything assembled easily. My boat loads easier and trailers better. Plus I have the piece of mind of having 4 boards vs 2. 401805

Parts were exactly what I needed, time will tell how they hold up with corrosion. I probably should of used 2x6 instead of the 2x4 bunks, but there was nothing wrong with these bunks. Time will tell how they hold up. 139758

After several attempts at finding the right clamps for my Surco cargo basket, we have a winner! The ones that Surco recommended for my Explorer did not work and they did not have alternatives. Amy was a tremendous help and even had the U bolts sent to her to verify the size before I ordered it. She also found the right size of shackle strap I needed to make this work for me! Thanks Amy and etrailer!! 58685

The U bolts shackle straps I ordered worked great and were high quality parts. I received my order faster than was promised. I will defiantly use these guys again. 13749
