I know this has been brought up before but I heard an interesting discussion at an RV show. The salesman and prospective buyers were deciding whether he needed aF250 or F350 to pull his new Rv.Neither of them mentioned gearing. I have 2 similar trucks in our small fleet.
2011 F350 6.2,3.73 11,000 GVWR
2012 F250 6.2,4.30 10,000 GVWR
The difference is in towing.
F250 22,000 GCWR
F350 19,000 GCWR

 

The deeper 4.30's will tow 3k more on paper whether 250 or 350. The 350 will have more payload on paper and will need dot certification when used in interstate commerce and even intrastate commerce in some states.

 

No brainer. In America bigger is better. 350 is bigger than 250. Got to be better.
I heard when I bought my 250 in 2000: insurance could be less on the 350 because of the purchasers of the 250 tended to be younger males vs professional tradesmen on the 350. Makes sense but I never looked into it.

 

An F-350 is bigger?

 

BY 100 !

It's ALGEBRA! ASSUME F=1

F250 + F100 = F350

 

BY 100 !

It's ALGEBRA! ASSUME F=1

F250 + F100 = F350


LOL....Make sense to me...LOL

 

Where I live they have a luxury tax on the F250s but the F350s are considered a "work vehicle" so they are exempt. With this, the cost is similar. My F150 tows enough but I can't put much in the bed while towing. I decided on the F350 6.7 as I plan on upgrading travel trailers in the next few years as I approach retirement.

 

Yes. A 2011-2016 F-350 is bigger than a 2017 F-250
