Follow-Up:
We have a 2003 Rialta. Bought it new in Dec. 2002. Have driven it 18,000 miles. Drove from Central Arkansas to California and return, 5,000 miles and 30 days on the road. Drove 10,000 miles and 60 days on the road to and from Alaska in July and Autust. The V-6 engine seems to have plenty of power to handle all conditions. We can't complain about performance. We achieved as high as 20 miles per gallon on one level segment, but moro often averaged between 15 and 19 mpg. Fuel economy depends largely upon terrain and wind, as well as how often you use the generator which feeds off the main fuel tank. All in all we enjoy our Rialta.
