We currently have an '01 chassis build date, '02 Class A Georgetown 32' rig. Very happy with the Ford part - Georgetown part is OK, but not spectacular. Since I'm a former motorcycle development engineer (Norton-Villiers), the high(!) revs of the V-10 don't bother me in the least. I was used to 4-cylinder 1-liter engines that developed their peak torque at 8,000 and peak power up around 15,000 rpm. 4000 rpm climbing a mountain pass is no big deal.
Since the rig had only 12,000 miles on it when we bought it at 8 years old and it's only at 18,000 now (12 years old), we can't address high mileage issues. It drives like a new rig and the performance is excellent. Ride quality of the F53 is not the greatest, but I'd rather spend my limited funds on going places rather than trying to make a silk purse from a pig's ear. It rides like the 11-ton box truck that hides under the RV bodywork!
We'll be putting it on the market shortly, as we can no longer afford 8 mpg and $4 a gallon on our limited retiree income, not to mention the $30 State Park and $50 commercial CG fees.
If anyone's interested, send a PM. We bought it locally after seeing an ad in our local weekly newspaper. We'll probably place it with a well-respected local consignment dealer about the beginning of October.
