I had a flat this past fall at the ramp, but had no jack. The jack for my blazer wouldn't cut it do to it being designed for the hole in the frame of truck. so I left boat at marina went home and got my 3 ton floor jack which weighs a ton. got back to marina and couldn't get jack under axle and was trying to jack on frame just in front of wheel but than trailer wanted to pivot. needless to say I had a hell of a time changing tire. So my question is what do you guys use to jack up trailer, and where do you guys store it?
