F-350 vs F-450

Thinking of upgrading to a Minnie Winnie 22M. Other than GVW, what would be the advantages of purchasing one on an F-450 vs. the F-350. Most of the ones I have seen are on the F-350 chassis. Also should I wait for the new 7.3 V-8 to come out.

Just like in Ford pickups, the F-350 chassis has a lower weight/cargo capacity than a F-450 chassis. The F-350 will be used on shorter class C coaches, the F-450 on the larger models.

The new 7.3 V-8 will likely end up in a new version of the F-53 motorhome chassis. Ford will probably change the van chassis sometime after they launch the bigger motorhome chassis. Given how things are changing, the big V-8 may never be used on anything but larger trucks and motorhomes.

We ordered the heavier E-450 tonnage on our Minnie Winnie 22M to assure we have ample payload to spare when towing. The only differences between an E-350 and a E-450 are about 250 pounds of additional frame thickness and springs, stiffer shocks, a wider rear track (75.4" to 77.7"), and the ring gear is increased from 10" to 10" diameter. The gear ratio remains the same, at 4.56:1. The 305 hp V-10 is a great engine, and the double-overdrive 6-speed automatic keeps the engine at about 2,100 rpm at 60 mph; just perfect!
If you decide to wait for the new V8 and 10-speed, keep in mind that it probably will be more expensive, as Ford will have less incentive to offer a discount on the Motorhome Prep Package. Pragmatically, the existing drivetrain is just fine. The advantages of waiting until 2020 will include a little more power, finer gear divisions, and a smaller dog-house around the engine (the new V-8 will be smaller on the outside that the current V-10).
