Quick Answer
Find RV-friendly Ford dealers by looking for commercial/fleet departments, calling ahead about chassis-only service, and checking RV forums for member recommendations.
The Rundown
Thank you for sharing this excellent Ford F53 motorhome service recommendation! Finding a dealership that actually works on Class A motorhomes built on Ford chassis can be incredibly frustrating, and your experience with Paul Miller Ford in Lexington, KY highlights exactly why having a reliable service contact is so valuable. The fact that they got you in on a "first come, first served" basis instead of making you wait 5 months, diagnosed your intermittent misfire issue (burned plug wire), sourced your missing front suspension bumper and rear sway bar mount, and had you back on the road in just four days is outstanding service for F53 chassis work.
Your experience demonstrates the importance of calling around when you need F53 service - that 2.5 hour drive to Lexington saved you months of downtime compared to the February scheduling you were facing in Knoxville. Mike the motorhome advisor clearly understands these chassis systems, which makes all the difference when dealing with the unique challenges of servicing a house built on a truck chassis.
Why It Happens
The challenge of finding Ford dealerships willing to work on F53 motorhomes stems from several factors. Most Ford dealers focus on standard pickup trucks and cars, and many service bays aren't equipped to handle the height and length of Class A motorhomes. The F53 stripped chassis used in motorhomes also has unique components and access issues that differ significantly from regular Ford trucks, requiring technicians who understand both the Ford drivetrain and the motorhome-specific modifications.
Your intermittent misfire caused by a burned plug wire is actually a common F53 issue, especially on older units where engine heat and vibration can deteriorate ignition components over time. The missing suspension bumper and sway bar mount you discovered are also typical wear items on these heavy chassis - the constant weight and road stress can cause mounting hardware to fail or work loose. Many general automotive shops won't touch these repairs because they're not familiar with the heavy-duty suspension components and mounting configurations specific to motorhome chassis.
The 4-5 month wait times you encountered in Knoxville are unfortunately typical at many RV service centers, especially during peak travel seasons. This is why finding a Ford dealer like Paul Miller that actually welcomes motorhome work and operates on a reasonable scheduling system is such a valuable discovery for the RV community.
Gather These Items
For other RV owners who might find themselves in similar situations, here are the key items to have ready when seeking F53 chassis service:
- Your motorhome's complete VIN number and Ford chassis serial number (usually found on a plate in the driver's side door jamb)
- Documentation of your Ford chassis warranty status and any extended warranty coverage you might have
- A detailed list of symptoms and when they occur (intermittent issues like your misfire can be tricky to diagnose)
- Photos of any obvious problems like your missing suspension and sway bar components
- Contact information for nearby hotels or RV parks in case you need to stay locally during repairs
- A backup plan for transportation if your motorhome will be in the shop for several days
The Fix
Based on your experience, here's the approach that worked for getting quality F53 service: Start by calling RV dealers in your area and asking for their recommended Ford service centers - they usually know which dealers actually work on motorhomes versus those that will just turn you away. When you call potential service centers, specifically ask to speak with someone who handles motorhome chassis work (like Mike, your motorhome advisor at Paul Miller Ford).
Be prepared to travel for good service, as you did with that 2.5 hour drive to Lexington. The time and fuel cost of traveling to a competent shop is almost always worth it compared to waiting months for local service or dealing with shops that aren't familiar with F53 systems. When you find a good shop like Paul Miller Ford, document their contact information and keep it for future reference - and share it with fellow RVers as you've done here.
For the specific repairs you had done, the burned plug wire causing your misfire is typically a straightforward diagnosis once they can reproduce the problem, but intermittent issues can be challenging. The suspension bumper and sway bar mount replacements are critical safety items that should never be delayed, as they affect your motorhome's handling and stability.
Know Your Limits
While some RV owners might be tempted to tackle ignition component replacement themselves, working on F53 chassis systems requires specific knowledge and often specialized tools. The plug wire replacement that fixed your misfire might seem simple, but accessing ignition components on these engines can be complicated by the motorhome body and auxiliary systems. The suspension and sway bar work definitely requires proper lifting equipment and torque specifications that most DIY mechanics don't have access to.
Your decision to seek professional service was absolutely correct, especially given that the work was covered under warranty. Attempting DIY repairs on warranty-covered items would have voided that coverage and potentially cost you significantly more. The fact that Paul Miller Ford was able to diagnose, order parts, and complete all repairs in just four days shows the value of working with experienced professionals who stock common F53 components and understand the systems.
For future reference, keep Paul Miller Ford's contact information handy and don't hesitate to make that drive again if you need F53 service. Quality motorhome chassis service is worth traveling for, and your positive experience there makes them a valuable resource for the entire RV community.
