Anyone towing with their 2.7 Ecoboost F150?

I thought the rule of thumb was 80%. That's what we were told in the TT forum, again and again.

Like others said that's a completely made-up rule. The tow rating is what it is. Having said that, with any vehicle as trailer weight goes up, performance, fuel economy and durability decline. The manufacturer's ratings are the "line in the sand" as determined by the manufacturer. Some folks like to tow with an extra margin to make for a more relaxed towing experience. Properly set up, I think virtually all trucks on the market can tow to their rated capacity with reasonable performance, safety and reliability. Having seen what you picked for a combination in another post, I think you will have a very well matched combo.
