For those with the 3.5EB, looking at an SCrew 6 1/2 bed 4x4 (I need a 6 1/2 bed) how is your empty mpg?
Do you notice a difference between 3:55 vs 3:73?

They get good mileage, but the reliability is suspect. My neighbor has one he's selling because it has left him stranded three times and it just got it back from a two week long visit at the dealer. Totally disgusted with it.

They have had their issues but ford is working on them. Tsb for timing chains and the like, improvements for 2018 EB's.

For the amount on the road, you only hear the bad, not the good.

I live 10 miles from work on rural 2 lane. Back and forth to work I get about 17 mpg. 75mph on the Interstate I get 18-20. A lot has to do with how heavy your foot is. I drive pretty conservatively. If the wife was driving it, you could knock a couple of mpg off of those numbers. I have 3:55 I believe. Mine is a '12 with about 60,000 miles. No problems yet.

I thought you only liked the tundra's? ��

I have a 14 with a 17 mpg lifetime average. I have had a flawless 25k miles, love the power at 7200 feet...

No complaints.

2011 4wd with 75k.
18 mpg but running a tuner. 8mpg pulling a 29ft travel trailer at max gvwr at 70-75.
One problem with brake vacuum pump in first year 2012 but warrantied. No other issues to date.

I have 3.73 gears and my father and uncle 3.55. I can tell a difference in grunt.

My truck is a 2012 4x4 3.73 Screw with 119,000 miles. I average 17.8mpg.

My Fathers is a 2016 4x4 3.55 Screw with 15,000 miles. He averages 19.3.

I drove his truck Thursday 50 miles round trip to the doctors for heart procedure but have never towed with a 3.55 version.

As for problems my family has 4 in the fleet. Not a single issue with any.

Reliability suspect? On a sample of one? I only have 14K on that engine (in a Flex) but folks are not having numerous issues with that engine; check the truck and Explorer/Flex/SHO forums.

No complaints.

I can buy a brand new F150 SCrew with a 6 1/2 bed for the price of a used Tundra.

After test driving both - I love the Ford, Hands down winner.

Since I own a Tundra, just curious why the Ford is a hands down winner? Not trying to argue, just wanting your opinion.

Toyota has always been very conservative, they seem to build very good products and then run with them for a bit to long before building to compete. My cousin has been buying new tundra's since they started building them, he just bought a 17 10 speed ecoboost for the first time, he is getting 24mpg and he loves the power. The Tundra was getting 12-14. The tundra is a solid pickup and most of them run like a clock but the engine design is old along with the transmission and suspension, they are late to the party at this point.

I'm on my third ecoboost and never an issue, the power and fuel efficiency of the ford is the cats meow for now.

I want a SuperCrew with a 6 1/2 bed, (electronic) locking rear diff, Toyota does not offer that. The MPG advantage the ecoboost has over the iforce is another reason. And the fact that i can buy a new Ford for a lower price with a lower interest rate makes it the winner in my book. The aluminum body is another plus, as are the ecoboosts.

The tundra is a nice truck, but the Ford fits my needs better.

All valid. I will say this-a lot of folks warned me about the 5.7 mpg, but we routinely see 17-18mpg. I can live with that. Now we bought our Tundra at year end and got it for 30k, 12k less than msrp. At the time it was cheaper than an equivalent xlt Ford with the 5.0. This was back in August of 2013. Strictly due to rebates and offers. Usually the Tundra is more expensive. I definitely have nothing against Ford, having owned 5 of them, currently own a 2013 expedition limited. This is our first Tundra and at 95k miles so far we are pleased.

I picked up a leftover 2016 F-150 got 13K off and 0% apr. it's a crew cab with the 3.5 eco but they only had 5.5 ' beds. We get around 19-20 mpg around town and highway. No complaints. My 2001 Elite gooseneck aluminum trailer still looks good. No major oxidation. Hoping the F-150 still looks good 15 years down the road.

I've only owned pickups with 8' and 6' beds so was concerned when I purchased my F150 with the 5.5' bed when it came to picking up lumber/etc and towing. Since I have a 20' gooseneck and a 6'x8' trailer the picking up materials thing isn't a problem, and the gooseneck is fine due to the design. I can pull a full 90* turn with it. When we get rid of our 2 horse slant bumper pull and go with a GN, I have a 10" offset B&W hitch to buy me more space between the cab and trailer.
