We were just looking at the MS at the RV show - I think it would be pushing it on my F350 DRW - yikes 23,000 lbs. The tires max load would be my greatest concern on a SRW.
I'm at 17220 GVWR (trailer) and 4,300 lbs pin weight and it tows smooth and nice, but in these mountains it is about the limit on this 6.7 DRW with 3.73 gears. If feels like there just isn't any more to give. With a MS, I think I would definitely be looking for the 4.30 gears in the F350 wide track or F450, at the very least, the new higher torque 6.7.
