As best as I can tell, my HF 1200# trailer has only about 2 1/2" of travel in the leaf springs before it bottoms out on the U-bolts or less than 3" until it bottoms out on the spring. The floor should have enough clearance above the tires for no problem. It will be very light anyway.
Also shown is a crude sketch of what the interior layout will be. You guys said you like pictures.....
