//speculation only

Be aware that towing capacity must be met with braking ability -- I drive the 3.5L ecoboost engine and it's engine compression is simply not up to the task on downhill driving of any slope greater than 4 or 5 degrees. Taking Bent Mountain on the Blue Ridge Parkway yesterday, 3 miles at 6-8 degree declines, the 3.5L kicked down to 2nd gear and I was forced to manually apply trailer control and foot brake nearly the entire way.

Thankfully I have the heavy duty brakes that go with the tow/cargo packages; and the blue ridge parkway at that section has pull-outs fairly well spaced out allowing me to give the vehicles a good rest.

If I were to consider the US or Canadian Rockies, I'd really want to look at a diesel I think....

Ian

OP: as suspected, more experience here with the 3.5 than the 2.7. For the $1200 or so I would step up to the 3.5

IanPoulin: do you mean degrees or percent grade?

But, no problems have been described regarding the 2.7L Ecoboost, despite that there are some out there. Nothing about mountains or engine failure.

Is the 2.7 supposed to get better fuel mileage than the 3.5?

By the EPA estimates a little better than the 3.5. Browsing online people are reporting above 20 average and up to 26 highway. It makea sense a little less ppwer and a little more economy. I suggest doing the research and forming an opinion.

You never want to start a trip worried about your tow vehicle trust me. 2015 ecobost super cab 4x4, best tow vehicle ever had, ALWAYS go with a little extra power it give you confidence to go anywhere.
Previous tow trucks, Chevy 4x4 5.3, 4x4 dura max, z71 5.3 suburban , none as good as my ford.
23 ft , 5 people,5bikes ,2 dogs ,tent and all the gear for two weeks ....12.2 mpg average in comfort, all weather. Never a question on tow truck over the tallest pass. We set out next year on 7000 + mile trip , no doubt 3.5 ford will do it again. Click image for larger version

The issue in comparing TVs doesn't seem to be its towing capability, because there are so many adequate options. The issue is controlling the rig on a mountain downslope. In this case a large bore diesel seems to be the remedy. I will eat crow, tolerate one 'daylight' being out and unfixable and look at a Grandpa Motors truck with a monster diesel.

I said look at one, not buy one. That would take a lot of convincing.

In the middle of our first trip with our 4th AS. 2010 Classic Limited 31. Our new 2015 F150 is just plain awesome. This is our 4th AS but only our 2nd TV. I am so impressed. The trip so far is 600miles. Look, I am not Consumer Reports, but this Platinum F150 4x4 is a rock star.

I would think that you are pushing the limit with payload.

Why? My 3.5L ecoboost carries 2700# payload - same frame a chassis, a 2.7L ought be the same when ordered with max cargo package.

We average 6-7K miles each summer, driving from CA to MT and Northwest parks... Used to tow from TX and no issues. Now from San Diego, past 2 summers in a row, towing the 25' AS outside Vegas on long grade both directions, the 3.5 EB quickly pegged red and overheated while going up the long grade....temp outside was 115+ both times at 60-65. (I know; speed limit is 55 in CA, but too slow with traffic flow.) Had to slow to 50mph and move into the truck lane to get it temp down each time...also had issues several times in Rockies going down long windy steep highway grades, where the "tow" mode did not proved enough engine breaking compression, even in 2nd gear...had to use the manual "tow break" inside to assist with the F150 breaking. I have the Platinum, Supercrew, 4X4, 2012 shortbed F150 model with tow package...contemplating next TV as a result of these issues. Otherwise, love the truck. Will see about new F-150 with newer transmission next year, and also check out the diesel..May look at Chevy and Dodge also...hate to go Diesel, but may be the cure...just don't want to buy a 250 if I don't have to...too much truck for everyday driving around town, parking, etc...
