I love my E/B with the max tow package. 365 hp with 420lb torque improves towing mileage. It has 90% torque from 1700rpm to 5000rpm. I have 3:73 gearing for 11,300# cap. It gets my 7000# 8280WS up to highway speed in a hurry. The tow package includes expandable mirrors, built in brake controller, 36 gal tank, screen display with brake value and accumulated towing mileage, retractable side box steps, on dash display checklist before towing, anti sway that applies trailer brake if it feels trailer swaying, transmission temp guage, oversized transmission cooler, and there's a hookup camera option I don't have. (not necessary for 5th wheel)
I'm sure I missed something. It tows a lot more than my 5.4 V8 at 300hp and 7300# cap. It's difficult to get over the V6 good, V8 better thing but I'm a believer.
With empty truck, I've been pulling G's re-living the feeling we used to get in the 60's with the old 427 Fords. It get's up to 60 in a hurry.
