RV at Sunset

Every week we take a look back at the RV Doctor Gary Bunzer's answers to your tough questions. He has been providing insight into troubleshooting, repair and preventative RV maintenance since 1968.

Where Is the VIN on My 5th Wheel?

I have been given a fifth-wheel that has no title. I am in the process of obtaining that, but need to know where I can find the VIN number. An internet search has proved fruitless and those responding often tell me to look on the tongue next to the bumper hitch. ObviRVously, they don't know what a fifth wheel trailer is. I'd truly appreciate your help. I do enjoy your information coming to my inbox every week- I'm learning loads! thank you in advance. — Tina G.

The RV Doctor's Orders

Tina, for towable recreational vehicles, fifth-wheels and conventional travel trailers, the Federal certification label with the manufacturer’s VIN is typically found on the left, roadside front corner of the coach, near the bottom of the sidewall. In some cases, it may also be posted inside a cabinet door or even on the entry screen door. But the required spot is at that front left corner, down low on the sidewall. Here's an example provided by Keystone RV.

All effort is made to ensure the correctness of Gary’s responses; however, not all responses will apply in every instance. Some situations may mandate a visual inspection and further hands-on testing. It is imperative that if you choose to follow any instructions or procedures outlined in The Doctor’s Orders column, you must first satisfy yourself thoroughly that neither personal nor product safety will be compromised or jeopardized. If you are in doubt or do not feel comfortable about a procedure, do not continue. Simply call your local RV service facility and make an appointment with them. Remember, the advice, recommendations and procedures offered by The RV Doctor are solely those of Gary.
