Daniel, I have to remove my extension every time I put TwoCan in the garage just to allow the rollup door to clear on the way down. Yes the dang thing is heavy and must be something like 8' long...never measured. I could never envision needing more than 6' and thought about having a trailer place saw off a few feet to reduce weight. Anyway, I use whatever is handy, like a 5 Gallon paint bucket, as a fulcrum...simply pick up the hitch end of the extension and drag it over the top of the bucket until you have the leverage to push down and navigate the other end into the receiver. Once in, just slide until holes match then set pin. Reverse process to remove. I wish the trailer has stopper pins so that I could drive slightly fwd or back to extend or collapse at the ramp with holes aligned without unhitching the boat. A trailer design flaw. Have to instead: 1) set fwd wheel down 2) Unhitch 3) Remove pin 4) Move car 5) Slide extension 6) Move car back into new position 7) Lower hitch and secure 8) Front wheel up What a PITA ... So I don't often do it, instead my trailer extension is one hole further out than fully collapsed and that is the compromise that works for me.

I tend not to use the trailer extension because the thing weighs a ton, and seems to be really hard to deal with. Anybody got any suggestions on how to get that extension in and out without killing myself, and lining the holes up easily?? Daniel Rich M#208 Kestrel
