This post is more applicable to this thread not the 3.0 PSD thread so I reposted it here. Oops
Christopher, I can tell your a thoughtful guy with all the research you’ve been posting regarding the 1/2 ton vs hd decision. I’ve had to make that decision recently myself.
I live in the Midwest so a snowmobile trip out west for me is 3000 miles round trip. We do that twice each year with some other family trips around Wisconsin. So I tow about 8,000 miles snowmobiling/year. I also tow my 8,500 lb boat about 1,200 miles each year.
I had a 2011 3.5 ecoboost that I drove for 60,000 miles and now have a 2017 f-350 SRW 6.7 PSD. Both trucks were CC short box. In between these two trucks I had a 2016 Chevy 2500 hd ( I got rid of it way too many problems).
The 3.5 ecoboost is an absolute monster, and now that it has the 10 speed I am sure it’s even better. I know the number don’t say it, but it felt like it had the same power as the stock LML on my 2500 hd. I did plenty of 400 mike tows with an 8,000 lb enclosed trailer. It was absolutely no problem. Now the 6.7 is on a whole different level when it comes to towing. I think most of that is due to stability of the chassis/truck itself. The power is obviously noticeable but not as much as you may think (for the 8,000 lb load). Now the f350 really shines in the 18 hour long tow session. You don’t know the trailer is back there so there is no driver fatigue.
I believe the 3.5 ecoboost is more capable than the f-150 chassis, but there are a few things you can do to drastically improve that. The most important is to get some D range or 10 ply tires the minute you drive it off the lot. The other is to get air bags for the rear end. Third is the weight distribution hitch.
The ride difference between 150 and 350 is huge. The 150 turns easier, sharper, and rides like a luxury sedan. I have a Honda Accord I use for daily commuting so it’s not much of an issue for me. Mileage is equivalent between the 6.7 and 3.5 ecoboost with diesel being more expensive.
I have no input on the 3.0 PSD except to expect issues for the first couple years of production.
