My garage opening is 107″ with the trim, 108″ without trim. I have a classic on a tandem axle trailer and have to approach it as an angle to get in. I have to be careful but I CAN do it. Its like threading a needle. My wife says that if I can back the boat in like that I ought to be docking the space shuttle. I think the total width on the trailer is 98″ so if I had a straight shot back I would have 4″+ cushion on each side. My trailer does have a pop axle but I havent used it yet. I could move the rig around by hand and line it up better if I used it, but, what kind of a challenge is that?? I hope I NEVER have to eat my words!! LashCat
