The car positioning will have more to do with the "tongue weight" exerted than where the car sits comfortably in the trailer. Find out what the recommended "tongue weight" is on your trailer/vehicle. Then put a scale under the front jack and move the car forwards and backwards to achieve the desired "down" weight. If you have too much weight "forward" the trailer will be squirrely & fishtailey as hell and too far back it will be lifting up on the rear of your vehicle and you get a floating, bounce ride. It's not hard to do but it takes a little bit of "jockeying" to get it dialed in. It's got to "ride" level too. You will know if it ain't right when you tow it cause it's a little scary feeling when she ain't right. I don't have a 20 ft trailer but I have two 16 footers and we have always set it up this way. My boats were the same too.
