Just remember to take BOTH end caps off the tube when you launch the boat off a ramp and sink the trailer.
SINK THE TRAILER???? why would you need to put your trailer more than 1/2 wheele deep?
Well of course you don't need to sink the whole trailer. In fact, just get to where the transom begins to float off the cradle and push it off. But as you're looking in the rearview mirror for the stern to begin to float and instead the whole boat and trailer begin twisting and heeling 20-deg to starboard... Ummmm... YIKES!
Ah the things we learn by doing them the stupid way! That which doesn't kill you...
