I got my 210 into my 22 foot garage going straight back. You do have to take off the platform, and when you take into account the speedo pickups you literally have about 6 inches between the front and back, so you need to be very careful.
I have an Eagle trailer that looked just like Graham's. I took it to the guys at DHM trailer in Sacramento, and they modified it to make it a swing-away tongue keeping it shorter than the front of the boat. couldn't believe what an amazing job they did, looks totally stock.
Also, depending on the angle of your driveway and height level of your hitch, you may not have to hand-roll the trailer in. We got mine in...barely. I've attached a pic of the tongue...
