Motor home chassis pro's and con's

Check the GVWR on both the Ford and the Chevy. In older years the Ford was rated significantly higher than the Chevy. If you see older P30 chassis on the road, they usually look like a kneeling bus because the front springs sag over time due to being at, close to, or above GVWR most of the time. Ford F53 chassis typically have 19.5" rims, not so the Chevy.

I think you have wheel sizes backwards and unlike Ford, have never seen a Chevy with 16" wheels.
As for the front end, the weight is usually within specs, but since the OEM coils weren't sufficient and have air bags, then a replacement with Henderson super steer replacements, works wonders for restoring ride height.
With rating being higher on the Ford, it was with the GCWR mainly and all because of the tranny that might overheat on long steep grades when pulling heavy loads. Still not a problem in most cases, if you know what you're doing and the 4L80E was a very good transmission overall.
Having said all this, I think the OP would most likely be going with the WH W chassis and the Allison tranny, anyway, if not going with the Ford.
