2018 F-350 - Three Questions

[CurtPutnam]

Question 1) - Is a 2018 F-350 SRW Supercab configured for maximum towing and payload adequate to pull a 5th wheel under 15,000lbs.?

Question 2) - Does anybody know if handicap paddle controls (in general) interfere with factory supplied brake controllers? 3rd party controllers?

Question 3) - Saw a Titan fuel tank display last weekend and wanted to query the wisdom here assembled about the advisability of a large (20 - 30 gals), gasoline tank in the bed. The ad suggested a tank with a feed direct to the gas filler tube which may have had a transfer pump involved.

TIA for your thoughts

Q1: If you are talking 6.2L Gas then you would need to see the Payload on it to see if you have the 3,000 pounds available for the pin weight along with everything else in the truck.

If you are talking 6.7L Powerstroke then you would have enough if it configured for maximum towing etc. as the max tow weight for the diesel would be about 5,000 pounds higher than the gas.

We are doing preliminary research for a F350 SRW (or similar) and we are going diesel. Then we don't have to worry about it if we decide to go bigger on the trailer when we get to that point.

So areyou concerned that the 48 gallon tank will not be big enough?

Don't see the 2018 towing selector but it looks like it would be real close on the 2017. The MOST you could tow would be 15,000 or less depending on the config with SRW. Maybe a DRW should be considered for 15,000 lbs.

#1 The F350 would be fine for towing the weight, however looking at question 3 it appears you are looking at a 6.2L gas motor - if you are going to tow a lot I would think about a diesel. I had that motor in my last truck and after a year of towing my 16,000 pound fifth wheel I upgraded to a diesel.

#2 I would not think it would interfere - as I understand it the brake controller works off a pressure sensor on the master cylinder.

#3 You will have a hard time finding an aux tank with a transfer pump for gasoline. Most companies only sell them for diesel for direct feed.

When you start towing a trailer that heavy, you will want as much fuel storage as you can get - trust me!!!!

P.S. with the 6.2L gas motor he will be lucky to get 8-9 mpg towing - food for thought!

I have a F350 diesel SRW and my truck wouldn't have anywhere near the needed 3,000 pounds needed for pin weight. My total carrying capacity is 3,300 pounds.

If you added the extra fuel, you will exceed capacity even more.

[CurtPutnam]

We are constrained to an LOA of 20' - HOA restrictions require that the truck fit in our driveway, So a Supercab with 6' 9" box comes in at just about 20' Gas tank on the Supercab is 29 gals - so that is about ~ 200 miles.

[Restcure]

To play devil's advocate, the gas truck will have a lot more available payload than a similarly equipped diesel.

[mbbutler]

Factory tank typically outlasts a bladder. Think about it.

[timfromma]

Diesels are great. They give you greater torque, get better mileage, you can easily fill up at truck stops rather than fighting the narrow gas lanes and the exhaust brake makes going down hill very easy.

Diesel drawbacks include higher vehicle cost and reduced payload capacity due to the heavier engine.

[timfromma]

For a 15,000lb 5er, you can expect about 3000lbs of just pin weight. You'll need additional capacity for passengers and other stuff in the truck.

When looking for my truck I opened a lot of doors checking the payload numbers. I bought a 2016 new F350 4X4 SRW 6.7 Lariat. Any package higher and payload suffers a lot more. My payload is close to 3500. My Montana gvwr is 15,200. Scaled ready for 3 months snowbird I'm at 14,150 and PW is 2670. PW will heavily depend on floorplan. PW and lack of pass through storage space eliminated thoughts of a 2017 Montana front living and front kitchen. 200# hitch, the 2 of us, small dog, and cooler leaves enough payload and we are under all other weight ratings. Trailer is 43' and tows better than anything I've had in the past.
I considered a 32 gallon aux fuel tank and decided nothing larger than the 20 gallon from RDS was needed. Finding a diesel tank that gravity feeds is easy. Finding a gas tank is a challenge. I'd never pull anything over 10,000 loaded with a gas engine, JMO.

If you get the long bed 2018 F350, it comes with a 48-gallon tank. Doesn't matter if it's gas or diesel, you get a 48-gallon tank. Get the short bed and you get a 34-gallon tank. Food for thought.

[CurtPutnam]

I am HOA length restricted. Need at least a Supercab so we have a place for our GSD. My wife will not have a dually and neither of us wants to go diesel. So a 6.2L gasser Supercab is the name of the game. Specs say I can get a payload over 3000 lbs and a tow rating way past the 9000 GVW of our trailer. We want to stay under 10K for pull trailers and 15K for 5ers to avoid the need for a class A license.

With a gasser I'd stay around 10,000 on the 5er too unless you can stay on flat roads and have no head winds. There are quire a few out there to choose from.

Man- wish I had the 48 gal tank. I have a 2016 F350 diesel lariat Long bed and have a 38 gal. Tank. Be nice to have 10 more gal built in.

More fuel = more weight = less payload. If I can get at least 350 miles per tank while towing, I'm happy. I can haul 700 miles per day and the mid-day fill is a good time for a stretch.

[jgump]

I hear ya. My max CCC is 3300. Just be nice to have even more time between fill ups when not towing.

[timfromma]

I can go 600 miles on a tank when not towing.

[jgump]

I'm less than that because my commute to work is so short. Never have long stretches of high mileage. I'm in the 400-450 range.
