I'm sorry for the newb questions, but I tried searching and didn't find exact results I was looking for. I know the below is subjective, but please try and be nice with my newbness and as objective as possible.
2015 F250, 6.7L diesel, Platinum crew cab, basically bone stock. I do have the factory "heavy" front end, it's on factory sized Fuel wheels (20") on 35x12.50's with a steering stabilizer and has a roll up tonneau cover, and has Airlift helper air bags in the back for towing.

I'm thinking about doing some light work to it.
It has the undersized 26G fuel tank. I want more range. I don't need to go boss sized, just more than 26G. Looking for easy take out of the factory tank, swap in the new tank. Not looking for anything like past rear axle or in the bed, aka a transfer tank.
I've seen the S&B (56G from them, 56 Gallon Replacement Fuel Tank for 2011-2016 Ford Powerstroke 6.7L Cr – S&B (sbfilters.com) and Titan (50G from them, 2011-2016 Ford Crew Cab, Short Bed SUPER SERIES (7020211) (titanfueltanks.com). Are these the go 2 aftermarket tank manufacturers? Pros and cons of each? It appears I have a skid plate around/on my factory tank setup? Would like to retain if possible. I also want the highest hanging aftermarket tank possible, e.g. I don't want one hanging real low. Best option?

Also looking to the following parts mods:
Cold Air Intake for 2011-2016 Ford Powerstroke 6.7L – S&B (sbfilters.com)
Cold Side Intercooler Pipe for 2011-2016 Ford Powerstroke 6.7L – S&B (sbfilters.com)
Body Mount Kit for 2008-2016 Ford Super Duty Crew Cab 5.4L, 6.2L, 6.4L – S&B (sbfilters.com)
MAP Sensor Spacer Kit for 2011-2019 Ford Powerstroke 6.7L – S&B (sbfilters.com)

Good or bad? Worth the cost? Better brand/version available?

I also saw that S&B is coming out with a hot side aftermarket pipe next month? Should I buy too when it is available?

 

I want to increase my range as well. You must have the short bed like I do... I like the Titan 50 gallon tank opposed to the S&B 56 gallon tank because the Titan tank doesn't go under the DEF tank like the S&B 56 gal tank as the S&B has a small lip that goes right under the DEF tank. Ask @Dirthawg2.0 that's how I realized that... Both of them hang lower, but not by much, so the factory skid plate can't be used with them.

I looked at all brands of aftermarket CAIs and finally settled on two; Banks and AFE. The newer trucks, 17 and up, Banks uses what they call their Big *** filter. If they would have redesigned their 11 to 16 6.7 air intakes to use that filter, I would have gone Banks. But I liked that S&B redesigned their 11 to 16 air intake twice. If they update the intake again, you can buy the new kit at a discounted price.

The filters are a little cheaper than the Banks and bigger. But that said, if Banks made a Big *** filter intake for our trucks, I would have bought it.

I have a Rudy's diesel CAC cold pipe on mine... if I were to do it again, I'd go with an SPE cold pipe.

I wanted a set of the S&B body mounts also until I saw SPE's body mounts... they are more but IMHO, they seem like a better set.

As to the hot pipe, that's up to you. I'm a fan of improving the flow of gases through the system. When I upgrade my CAC, I'm going to buy a Mishimoto, I will buy an aftermarket hot pipe as well.

As to the MAP sensor spacer, I don't know... ask @speakerfritz because he installed one.

Here's my S&B air intake thread in case you didn't see it.

Welcome to FTE... I'm no expert. I just read a lot and learned some stuff from being here...

 

It's a crime that Ford allowed a 26 gal fuel tank on an F250. The fact that a 60 gal aftermarket can replace the undersized fuel tank means Ford could have installed a larger tank or allowed it as an option.
If I would have known about the undersized tank I would have bought the long bed version of the F250.
I tried justifying installing a larger tank (~$2000 including labor) but I rarely pull a trailer or camper but if I did there is no doubt I would upsize.

 

Thats the problem with my 2016 SB. 26 gallon tank. When towing my 16K 5th wheel, I get about 200 miles range, thats it. I mean i like to get out stretch about then, but some roads are a bit sparse on fuel stations enough to make me sweat. Ive got a 2023 on order and went with the LB with 48gallon tank specifically for that reason. Now if Ford can just get the dang thing built.

 

Yeah I don't pull anything but still feel the 26 gallon is a PITA. Can't imagine what it's like for a guy pulling a 5er.

 

One of the best mods one can do is change out the 26 gallon tank on the SB. I changed mine out to the Titan. No more searching for places to get fuel after 200 mi. The 50 gal from Tian sits about 2" lower than stock.3-3" wide heavy duty galvanized straps support the 50. I had Ford replace it for me and a recalibrate.

 

I like the Titan 50 gallon tank also... I have a thread from FORScan's forum printed out on how to do a recalibration with FORScan for swapping out to a bigger tank.

 

I looked at the replacement tanks, had a hard time justifying the cost above and beyond the cost of the truck. In the past I was selling every 5 years due to mileage driven.
