Walter, I have several suggestions:
1. Knowing what kind of MH you have might help guide you to better service options.
2. I'm not aware of many "one size fits all" service locations. By that I mean that the best places for working on RV appliances like furnaces, water heaters, etc. may not work on chassis items like engine or transmission maintenance. Knowing what kinds of service you are looking for might also get you better ideas for service locations
