The main reason that I wanted the extension rack was to carry my inflatable pontoon boats from base camp to the hard to reach fishing lakes in the high altitude mountains of Central Utah. The more I use the extension rack, the more I like it.
When I first got the extension rack, I found it to have sharp edges that needed to be filed or ground down. The tips of the rack were sharp and uncovered. I feel that S&T should provide an end cap for safety reasons. Now that I have filed the sharp edges down, it is less likely to hurt me if I walk passed it too closely and brush my arm or clothing against it. I would feel better about my expensive pontoons sitting on the rack if there were protective caps.
The rack is very configurable. I have two main configurations for my needs. One is a transport mode that cinches everything up making it smaller and easier to maneuver around tight trails. The other is pontoon boat mode where I extend the sides and flip them over to keep the boats from sliding off the side.
The rack comes with bolts to keep it together and I found it more convenient to use quick release pins. The only issue with using the pins is that they don’t keep the rack as tight and it becomes noisier on the bumpy trails.
Bottom Line:
The extension rack is worth extra investment to make you Mountain Goat trailer that much more versatile.
