I'd buy a slightly used crew cab 4x4 F250 with the 6.2 and call it done ....my experience in the owning your own busines thing is to keep your overhead as absolutely low as possible in your case I'd even think of keeping the F150 if it's still reliable and just keep putting money into it ...my business was a truckmounted carpet cleaning service and I always thought having new pricey equipment was necessary but after working for two of the largest privately owned companies in Arizona and seeing how they did business it was definitely an eye opener ....good luck

 

To me it sounds like an F250 would be more in line with your needs. The F150s are perfectly capable of towing heavy loads, but the F250 is going to handle the weight with a little more ease and last longer under those severe conditions. To me, if you're much more than a weekend hauler, you should really consider stepping up to a 3/4 or 1 ton truck.

 

I am a 150 owner and I love the 150 platform. With that being said, if you really are going to tow that much weight that often, get the 250!!! It is designed specifically for that kind of work. The 150 has a broader design requirement (i.e.. comfort, lower price points ...). The 250 is a rock solid towing work horse.

 

IMO if you are going to tow that heavy that often, the 6.7L is the only choice. and if you're buying new, a 2016 KR F-250 6.7L has an out-the door price nearly identical to a 2016 F-150 3.5L KR because the 2017 superduty is hitting showroom floors. You don't get all the technology or the aluminum body, but having towed quite a lot myself with gas and diesel and now (only a little bit) with the EB... it's not even a valid comparison. the diesel is playing a whole different game. towing with one of those feels like you're just doing the thing the truck was designed to do. it does not feel like you're asking it to go above and beyond, like it does with a gasser (even a 250 gasser).

In my experience, towing 3-4k with a gasser, including the EB, is a non-issue. towing 8-9k with the EB isn't nearly as comfortable. towing 10k with a 6.7L 250 is a dream. I had about 5k in my 1500lb steel wall big tex trailer today and pulled it to the dump. 6500 lbs trailer weight. it went fine, no problems... but it was nothing like the 6.7L was.

my 2 cents - go diesel. it's cheap to get a 2016 right now and you won't regret it. it's the right tool for the job.

 

If you're pulling a trailer for a living, then get the SD. A 6.2L with 4:30 gears and without all the fancy electronics. You've got brakes, tires, axles, bearings, and a host of other things to think about not just door jam capabilities.
