Not only do you need to consider the distance between the fence, but also the setback from the road and the length of the home + toter.
The best information I could find on mobile home turning radius and sweep paths was from a university of michigan study below. Check out pages 50-54…hopefully this provides some rough guidance.
Worst case you can remove an endpost for a move to get the extra clearance needed - these 3 rail fences are pretty quick to assemble and disassemble, but digging a post out might not be so much fun.
