The EcoBoost and EcoDiesel will be a total toss up. I wouldn't suggest the Pentastar because you can quickly get over-matched if you upgrade TT's.
I have one friend with an Ecoboost. He loves it and unloaded MPG is great. Towing it drops under 15MPG quick. He barks about the towing mileage but in terms of power it has plenty. I'd go with the 3.5L as the 2.7L could run out of grunt....again if you upgrade TT's.
I don't know the towing fuel mileage on the EcoDiesel but I think they are rated at something like 27MPG highway unloaded. That's awful nice :B
I don't buy the maintenance cost argument in the gas vs diesel debate. I do my own maintenance so my only costs are supplies. Every 15,000 miles my RAM 6.7L Cummins requires 3 gallons of oil ($22/gallon), a $10 oil filter, and 2 fuel filters ($60 total). So basically once a year I put $136 into routine maintenance. My old Chevy with 6.0L required 6qts of oil (about $35) and a $5 oil filter every 5,000 miles. At $40/oil change about 3 times per year I spent roughly $120 on supplies for routine maintenance. Both are using full synthetic oil and quality filters.
So the diesel costs $136/year for oil and filters and the gas cost me $120. Are you really going to get worked up about a difference of $16/year? I'm not. I'll take the power and capability of my diesel every single day. I'm not about to bash my old truck.....no way. It was reliable as can be and served me well for 10 years, we simply jumped up into 5th wheels at a weight that just wouldn't work with the old gas engine.
In your case you have legitimate choices of gas vs diesel. I just think you need to decide which truck you like best (F150 3.5L or Ram 1500 3.0L) and go with it. Either one will serve you perfectly well. The maintenance cost argument just isn't the big deal some folks make it out to be.
