Since you have looked at Workhorse I can give my comment on having one for 11 years. I had a 2003 Mountain Aire 38' on a W22 chassis. Some complained that it was not enough CCC. I weighed each wheel position and was never close to over loaded, even with full water tanks. There was a recall on the brakes for the W20 & W22 chassis. The W24 had different brakes. The recalls have been done as far as I know. I had great MPG when I had that MH. I got 8.5 overall when I sold it and was never without a toad. The 8.1L engine is larger than the V10 Ford in Cubic Inches but it runs a lot slower so there is never the engine racing noise. In 2005 the Allison transmission came out with 6 speeds and grade brake that would automatically downshift when you tap the brake going downhill. Ford was always trying to catch up to the Allison Transmission. Parts are not a problem since there are so many Chevrolet trucks on the road. The ride was a little smoother than the Ford of the same vintage.
