.... I haul my 6500 lb horse trailer all over with my... wait for it... JEEP. Yup, 4.7 V8. I know, it's not the safest rig, but I've never had a problem with my transmission or my engine. As a matter of fact, it's got plenty of power, even when fully loaded. I've hauled for over 8 hours, didn't think anything of it. It's been hauling regularly for 4 years now.

Yes, I understand that dangers of towing with my rig. I can't afford a truck, so I work with what I've got, and it does just fine.

How on earth does your F-150 have a lower towing capacity than my Jeep?
