My wife and I are considering RVing full time and we don't know what the right thing to do is. We have looked at a 1999 Monaco Diesel 275hp Cummings with 72850 miles on it and a 2004 Georgie Boy with a Ford V10 and 33,000 miles. Which would be better the older diesel or the newer ford? We will be pulling a small car behind it. Both of these two motorhomes are listed at $25,000.
