Truck size recommendations

[rubberduckie]

Ok so I am more confused than ever. You have GVW, GVWR, RGAW, RGAWR, GVWR, UVW, GVWR/PNBV, GAWR, GCWR, max king pin weight. You have to have a PHD in weights and measures to figure out how large a Truck you need to pull a fifth wheel. I just need to know how large a fifth wheel I can pull with a 2020 Ford F-350 crew cab diesel with 3:55 gears. Just me and my wife not my extremely over weight mother in-law and her three pound lap dog.

I think posts 2 and 3 answered your question. That's a heavy trailer, so a 3/4 ton is out of the question. It's not what you have inside the cab that matters that much. Personally I'd go for something with a dualie rear axel.

I get the Montana is out, don’t want dual axel truck. Trying to figure out how large a fifth wheel I can tow with F-350 single axel.

I believe page 12 of this PDF will give you the max cargo weights of the various models/engines. Note you have to take accessories, other cargo and passengers from that number, so SRA won't leave you with that much. Edit: There is apparently one configuration with a 4,500 capacity!

If it were me I would not want to go over about a 13k trailer (GVW of the trailer) with a srw truck. Assuming 25% pin weight 3250, hitch 200, you and wife 300= 3750lbs with a few hundred lbs of payload left over for fire wood, tools or whatever in the bed of the truck.
Too much more than that and you are going to start hitting tire capacity limits and getting close to rear axle limit (7200lbs I think) without that extra set of tires on the axle.

this also assumes truck with a 4200+ payload ability

350/3500 SRW...14K GVWR trailer MAX

[tuffr2]

I kinda agree with Old-Biscuit that you could use a SRW F-350 with 8' bed and payload of 4,300lbs.

You would be much better off with a F-350 DRW (Dual Rear Wheels) for comfortable driving however.

The model number 381 tells me this is a long trailer and toy hauler tells me it is a heavy trailer. If it was a model number 321 that is a SRW model number. 381 tells me a dually would be best.

I would be a nervous wreck with a SRW truck towing that trailer...one rear tire blowout and who knows what will happen.

Read the my post #3 - that information is more true than not.

I've not discussed pin weight or size of truck at all, other than briefly agreeing with swavescatter's opinion in post 4.

So . . . .



Completely off point, irrelevant and non-responsive.

No you took the thread off track, the OP is looking at what size TV for the 5er he is looking at. For that need to know Dry, payload and GVWR. If the 5er is small with a huge payload you likely don't to look at GVWR.
In this case huge 5er (41' 9") and a smallish payload for a TH that size (3,454#) the OP should get a F350 DRW.

Read the ford towing specs............

Thanks

Lots of advice here and all is useful for you. Without getting into the weeds, others have and it's useful, you will want a diesel 350/3500 and you will want a DRW. No question based on my experience. That's a lot of weight to tow, and very importantly, to control and stop. Dry weights are of little use, loaded weights and GVWR's are key.

Well one needs to read all the towing specs and understand them. Towing is just not pulling it is also the ability to carry the pin weight.


With a diesel pulling is not the issue, with a diesel carrying is the issue.
In 2013 Ram started a SRW war, in that it took the GVWR of a 3500 SRW from 11,500# to 12,300#. That 12,300# was the GVWR of the 2012's 3500 DRW!


If you believe that two tires can support a load as well as four?


In 2019 or 2020 GM and Ford followed suit with over 12,000# GVWR on 350/3500's SRW, I think Ford is 12,500# and GM is 12,300#.


Payloads on these trucks (diesel) range about 4,200# to about 4,700#.


The scary thing with 5th wheels is that they are inherently stable, you can have an overloaded TV and the TV/5er combination will drive and handle pretty well, that is until something like a rear blow out on the TV happens.

No, I was responding to something someone else said that I believe is bad advice. But I'm glad you can understand that there can be more than one topic being discussed in a thread at one time. Old Biscuit responded to a second topic I was discussing in a way that was not on point and irrelevant.

I will note, however, that I also brought up toyhaulers possibly being different on that second topic. But I won't go into how, other than saying empty weight can be important too. So I will retract something I said or at least implied in post 4. I would pay attention to empty pin weight in a toyhauler. I was only addressing GVWR of the trailer as that might be considered with GCVWR when I was agreeing with ignoring the empty weight.

[Old-Biscuit]

No I was responding to OPs post and using DRY weights
GVWR gives one the FULL picture especially when looking at towing a HEAVY TH which is what OP was looking at

Post 11 you quoted me and thus presumably were responding to me. Sorry if you didn't understand the topic I was addressing in post 11.
