Good info and advice from yuppie_rednk #8. In general buying used, to some extent, you are buying someone else's problems. However, for many of us, used is the only way to afford a diesel pusher. My 99 had less than 15,000 miles on it when I bought it last summer. Even so, in addition to the purchase price, I planned to spend around $10,000 in maintenance, repairs and parts. The short of the story is, prior to purchasing the coach, focus on the big ticket items such as the engine, transmission/drivetrain, tires, batteries, brakes, generator, refrigerator, roof and roof ACs. Post purchase, expect to have issues and bugs that need to be ironed out - mine certainly did from disuse for so many years. The trade-off is, a lot more coach for the money for more work on your part to get it into shape.
Keep in mind, not all of the issues addressed in this forum apply to 98's. Also, from reading iRV2 you could conclude that Alpines are just a never ending string of problems. That is not the case. The strength of this forum is the collective experience of many Alpine owners who are willing to take the time to help other owners. That is a huge benefit for those of us who think Alpine is still one of the better coaches on the road today. You are welcome to PM with questions.
