I have recently purchased a new old Gulf Aero Light 19 ft bumper pull camper. The camper weigh 4005 LBs dry and about 4500 loaded with gear but not fresh water. I have a 2004 Lincoln Aviator with a 4.6 L 281 V8 dohc with 110,000 miles. The tow rating on the TV is 7000 lbs. Can I successfully pull the camper, it seems a bit sluggish? Could sure some advice.
Here's a trick to get better performance - put on the smallest tire with the highest payload that can match your factory rear GAWR. I believe it's 3400 lbs.
A 225/55R16 XL tire carries 1709 lbs @ 51 psi. 25.7" diameter. OEM is 29.5". It's a 15% gear upgrade at much lower cost.
If you have 3.55 gears, you now have 4.07. And 3.73 gears are now 4.28. It'll look funny, but the cheapest way to gain true towing performance. As a bonus your brakes will also feel much stronger.
