Follow-Up:
Rialta was my first motorhome, and I love it. No problems with it in three years, except tires. Can't find any that fit in the major brands, except high dollar Continental. But, would rather pay $1,000.00 in tires and keep the Rialta rolling, than give up all the fun it has given Michelle and I. On our trip from Utah to Florida our mpg was from 17 in the mountains, to over 19 on flat roads. No problems at all, except tires. Anyone have suggestions on tire replacement?
