I'm now beginning to see postings in the forums by owners who have Class C motorhomes based on the Chevy 4500 chassis - a much better chassis for a Chevy-based Class C beyond about a 24 foot length, IMHO.
I'll bet the 4500 Chevy chassis has lower differential gearing than the Chevy 3500 chassis does - just like the Ford E450 does as compared to the Ford E350.
Hence, I'll bet that Chevy 4500 Class C's get worse gas mileage than the Chevy 3500 Class C's do.
Can anyone report on their Chevy 4500 Class C motorhome's gas mileage?
Consistently getting 10.5 to 11.2 mph with Chevy 4500 running 58 to 60 mph. Normally about 1700-1800 rpm. Full fuel and water tanks, 2 adults, and food and gear for week to ten days.
