Give me your opinion

I based my design on another outstanding members design. I am using a already built boat trailer to base it on and will be modifying it to fit the design I have. Give me your opinions and suggestions base on the below measurements. The trailer is much longer than in the drawing and I will be cutting it down to fit my needs but it is 72" wide inside the tires so this will be a wide Teardrop.
Thanks
