Hi teamam,
If you scan through this forum (use the search tool in the upper right corner on words like "service", "dealer", etc) you will find that getting timely service from even your selling dealer is often difficult. Universal warranty coverage, as is common in the auto industry, just does not exist in the RV industry. I would suggest that you talk with nearby RV service facilities, before you arrive in their yard with a coach needing work. Another Grand Design dealer might not be your first choice. Grand Design has demonstrated that they will work with an independent service facility in your area, if this is where you can get reasonable turn around time on repairs. Sometimes, you have to pay upfront and submit your receipts to GD for reimbursement.
