Part of the learning process that begins when a coach is purchased is the development of a network of people to call when you need support.
Anyone that takes the time to read the forums is going to see a lot of posts from owners that can’t get the coach started, can’t get the coach to the driving height, or are experiencing other somewhat serious concerns such as a check engine light. First, recognize problems that are so significant as to stop you from getting anywhere for service are relatively rare. We are approaching 1400 members, and previous forums with active memberships also had a lot of Prevost owners but as a percentage of the overall participants only a very small percentage are really in trouble.
And when we get to the root cause of some of the type of problems owners face it is often found there is a fairly simple “fix” to get someone going again. Sometimes the “fix” is as simple as resetting a circuit breaker, or replacing a solenoid coil, or manually retracting a slide. Sometimes the problem is much more serious but those are pretty rare.
But the bottom line is that Prevost, Detroit or Volvo, and Allison for example are always going to be your #1 contact when there is a problem and I believe all offer 24 hour assistance. I cannot think of anything a converter needs to help with in the middle of the night, but I believe all of them have phone numbers they offer for help when needed.
Another source of assistance is another member who has your specific conversion and experience with that conversion. A lot of times owners learn the not so obvious things that help an owner such as where the GFCI receptacle is for the front or rear outlets, or how to reboot the house control system, or how to bypass an inverter to get the refrigerator powered up. Service support is a concern, and everyone needs to prepare in advance for the time when they might need some, but it is not now and never will be an issue that should influence the purchase of a coach.
