Diesel RV Maintenance Checklist

Because an RV is a huge investment, regular maintenance takes on added importance. But although we understand that maintenance can save us from incredibly expensive breakdowns and emergency repairs down the road, many of us aren’t familiar with our RV’s systems and what we need to maintain.

When we started fulltiming at the beginning of 2014, I kept telling Eric that we needed a comprehensive RV maintenance checklist. He agreed, but we were worried we’d leave something out. Imagine our gratitude when our friend Daryl Waldrop, owner of Iron Horse RV in San Antonio, told us he had a diesel RV maintenance checklist he would share with us! Granted, this list is from one shop, and your own RV mechanic may offer a slightly different list. But considering Daryl has decades of experience servicing RVs and is a diesel owner himself, I think this is a great place to start.

I did get approximate pricing from Iron Horse for each service item. I’ve debated about whether or not to include the pricing in this article because it won’t stay the same forever. But as long as you take the numbers with a grain of salt (and don’t get mad at Iron Horse if they change!), I think the info is useful as you plan and budget. Also remember that the figures will change from rig to rig (for example, some rigs have more filters than others).

I’d love you to comment with notes on your own maintenance schedule and what your experience has been. If you have questions about these maintenance items, I am the wrong person to ask! You’d be best off contacting Iron Horse RV directly, or reaching out to your own RV shop.
