Rear axle

I try to find out what the towing capacity of the 2017 F350 DRW but I can't find it.I got a 15000 LB FW and I try to see what axle is better for towing.Can somebody who know what better 3.55 or 4.10 .I got now 3.73 and I like it but Ford don't offer that no more.I like the fuel economy but I don't want to struggle in the mountains. Please let me know.

No one can tell you what YOU should buy. For gas and you do not want to struggle I would recommend the 4.10. If diesel the 3.55 should do you well. But these are just my opinions. I know many others would disagree.

Probably depends what percentage of the time your truck will be pulling that trailer.

I'd get 3.55. If you need 4.10, go with a F-450.

Don't believe the locking rear differential is available with the 4:10. Or it's just not available with F-450. So many freakn' options, it's hard to remember!

lol ok this is bugging me. Not trying to be offensive. It's 3.55 (short for 3.55:1), not a 3:55 ratio.
