We purchased this 170 on April 24, 2006, from retired private individuals who had used it very little. It has 43,657 now. These are easy miles as we did not tow nor push the engine hard. By driving conservatively, we were able to get from 13 to 17 mpg.
The first thing we did was add an Onan generator. It has only 24 hours use. We have “exercised” it each month for ten minutes under load as recommended by the manufacturer.
It has had regular service including oil changes every 3,000 miles. We added four new Michelin tires costing $858.00 a year and a half ago. They have less than 3,000 miles wear.
The computer on the engine was replaced in December of 2008.
We do not smoke, neither did previous owners. We do not take our pet when we travel. Previous owners stated no pets also.
