About same for the Fords. But they underrate the rear axles on SRWs.
The springs are the same for both F250 and F350 SRW. And to weak for towing compared to GM and same as Rams.

You guys are confusing terms. The axle rating and the gross axle weight rating (GAWR) are two different animals. Example: 2009 F-350 SRW 4x4 diesel. The rear differential/axle by itself is rated 7,280 pounds @ground.
Max rear GAWR for that truck with 18" or 20" tires is 7,000 pounds, so the rear axle is not the limiter.
Max rear GAWR for that truck with 17" tires is 6,262 pounds. So the rear axle is not the limiter there either.
The rear GAWR is affected by tires, wheels, springs, differential, axles and everything else in he drivetrain at the rear end of the truck.

Smokey, you are right on, but why do you want to confuse the ones that think they know the answer with the real answer?
I found a long time ago that that trying to educate some folks is like taking a horse to water...you cannot make him drink, just like you cannot make some people learn.

I agree with all of Smokey's statements, but I have to ask: what are the load ratings on the 17"/18" and 20" tires?

For 2009 F-350 SRW:
17" = 3,195@80 PSI
x2 = 6,390 on rear axle
18" for 4x2 = 3,415@80 PSI
x2 = 6,830 on rear axle
18" for 4x4 (optional on 4x2) = 3,640@80 PSI
x2 = 7,280 on rear axle
20" = 3,750@80 PSI
x2 = 7,500 on rear axle.

Don't put the horse before the cart, get the trailer you want before the truck, then figure out what truck you need and keep in mind a bigger trailer in your future.
My truck, 2011 Chevy CC short box, 6'6" Dmax 4X4 with me, 1/2 tank fuel, 5th wheel hitch, spray in liner and tool box with 150+- lbs of "stuff", weighs 8020 lbs, GVWR is 11500lbs, so with DW and full fuel I'm close, but within all limits and we are average sized folks.
Forget about the trailers advertised pin weight, mine was 2045 lbs, but in reality is 2850 lbs loaded for a winter trip, but I'm heavy with 4 6V golf cart batteries and a combo washer/dryer in the bedroom closet.
2X4 vs 4X4? I can't comment as where I live you cant give away a 2X4 truck, but has saved me twice towing when I was dumb enough to go where I shouldn't have, a very firm looking lookout just after winter breakup that was 8" of soft mud, and a very wet grassy spot that had a hill up to it.

We had an F450 4WD get stuck on the paved, flat street right in front of my house a few winters ago with large mud/snow tires. Of course the driver was dumb enough to attempt to turn around in the middle of a narrow street on rutted snow and ice. I got a kick out of it (after helping him out). Later that afternoon, I backed out of my driveway and drove to the store in a front wheel drive focus wagon.
Go figure.
Sometimes even the right tool can have the wrong driver.
