I also tow an
Escape 17B and wanted to open my tailgate. I tow with a full sized pickup truck so the tongue weight of the trailer is half of the max for my vehicle. I was quite comfortable extending the ball back a couple of inches. Plus the truck has the factory towing package so wider rear leaf springs etc.
I’ve towed from the Pacific Ocean to the Atlantic Ocean, mountains, prairie, high winds, rain never had a problem, never any sway. Extremely stable passing trucks or being passed.
Moving the ball further from the rear
axle does increase the length of the lever so will increase the apparent tongue weight the tow vehicle sees, the trailer tongue weight does not change.
I do not use a weight distribution hitch, if I did that would move ball back about the same distance.
