Some of the experiences in delayed service may be compounded by that time frame or time of year we need the repairs. If it's April, May, June and even July, everyone else is also trying feverishly to have their unit serviced. That next trip is the most important one. If the repairs you need are keeping you from being able to use your unit then yes, you must have it serviced but if the repairs needed are a "can live with" until the off season, then do so. Pick your battles with this very seasonal recreational activity. Also pick your dealer. From experience, I'm a firm believer that a Mom and Pop shop will give you much better service after the sale. From a purchase side, you generally with do better from a large regional or national chain. This has been my experience.
