BRP Trailer Module Kit

Thanks for the "heads up". I always inspect the trailer before, during, and end of the ride. Even with the cooler filled with ice and water, the weight of the tongue is under 30lbs. The aluminum tubing is 3" squared x 5/16" thick.

Should be plenty tough then.

Well, since we haven't had a dry weekend in months, I spent time working on the trailer. I buffed out a mirror finish...ok, almost mirror finish on the fenders.

I think I closed the gap now so that it will eliminate the rooster tail up the back of the spyder.

Good idea.

Keep an eye for possible cracking on the bottom side on the tongue. I used a 2" square .062 steel tube for the tongue when I made my trailer. There is so much bouncing and vibration from the hitch being mounted on the swing arm that the weight of the trailer and cooler causes a lot of deflection and stress on the tongue. Mine cracked all the way around to where there was only about 3/4" of steel on the top side pulling the trailer! Had it broken clear through the safety chains would have been pulling a 4' piece of tubing with a tool box attached. Who knows where the trailer would have gone!:yikes: A trailer tongue is subjected to much more up/down bouncing behind a Spyder than motorcycles like Goldwing and Harley where the hitch is suspended from the bike frame.

Wish I'd seen this before trying to lighten my steel trailer frame! Oh, well!

I think you seriously need to consider replacing the tongue. The reason being you have removed metal in the part of the tongue subject to the greatest stress. I fear you risk having the sides buckle at the top side where the tongue metal is in compression and split apart at the lower part of the sides where the metal is in tension. On the bottom side you are transferring a huge amount of the stress from the bottom side to the lower portion of the two sides. You would have actually been better off to drill smaller holes right at the centerline of each side. The center of a beam is subjected to very little or no stress where the stress transitions from tension on the bottom to compression on the top.

I'll keep an eye on it. Thanks.
