Rich suggested the VDU problem , the predecessor for the LBCU. I had the exact same issue with my 2008 Freightliner chassis mh due to a faulty wiring harness connecting the LBCU. I believe the VDU problem was a weak solder joint, right Rich?

Can you hear any leak(s) near the rear air bags.

I think you need to call the 24/7 Freightliner help desk and get their opinion.

Now that you're part of the Newmar family, I recommend you call the Newmar Customer Service number and talk with them. Ask for an Essex specialist to help you. You will need either your Newmar Unit Number or your VIN number. You may also want to join Newgle, the Newmar knowledge base online system. https://www.newmarcorp.com/owner-tools/newgle/ 1-800-731-8300

Michelin specifically states to begin inspecting tires after five years. Of course Michelin has been the tire manufacturer with most of the zipper blowout issues.

Do you need some information about the codes? If so, you can call Cummins customer Assistance and they can tell you. https://www.cummins.com/customer-assistance

BTW....even though the original poster hasn't been back to post, I apologize the thread took a turn after tiremans post asking for our agreement on his financial analysis and running tires for 10 years.

The following information is copied from the Michelin Tire website. 1- Keep five years in mind After five years or more in use, your tires should be thoroughly inspected at least once per year by a professional. 2- Ten years is a maximum If the tires haven't been replaced 10 years after their date of manufacture, as a precaution, Michelin recommends replacing them with new tires. Even if they appear to be in usable condition and have not worn down to the tread wear indicator. This applies to spare tires as well. This brings up another question that Tireman has also recommended, have the tires thoroughly inspected at least once per year by a professional. I've never seen a tire shop that employees someone I would trust as a professional tire inspector.

I don't go 8-10 years on my vehicle tires and would never go that long on a Class A Diesel Pusher. In my opinion, the original poster purchased tires that have a useful life of 3-4 years, therefore it was a terrible financial deal.

If you want to take the easy way out, call Magnum and they will patiently step you through the setup. Magnum tech support: 425-353-8833

If you keep testing you are bound to get a passing grade. LOL

You answered questions in this post you had answered in your previous posts yet you ignored the only question I asked in my quoted post. "I guess I need a definition of "operated". Many times I've slowly driven a few hundred feet on a flat tire to a safe area before changing the tire. I have taken the tire in for repair and then safely used it for many more miles." Perfect example: I replaced the tires on my previous motorhome and the installer failed to tighten the metal valve stem properly. I drove the motorhome home and stored it inside my building. Three days later I noticed one front tire was low and measured the pressure to be 65 psi. I aired the tire up to the recommended pressure based on my front weight to 110 psi. Based on your statement, if a tire is "operated" flat after losing 20% of the minimum air pressure then I drove for 5 years and 30,000 miles on a tire that was not safe. Unless and that was my question, since I never operated (drove) the motorhome, was I safe. Can/will you give me your definition of operate. Personally, I would think a tire that needed 110 psi parked for three days at 65 psi would be as dangerous as a tire driven 100 feet at 65 psi pressure, but then again, I'm not a retired tire engineer. Thanks and I would appreciate your clarification. Oh, and I pray a lot more engineering goes into tire design than paperclip design. LOL

Mjarry, I too am interested now that you opened the door. What do they say about us Texans? Mailman, I have a Winegard Traveler mounted on my Class A diesel pusher and it sits lower than my a/c units during travel. You do understand it folds down when traveling.

Since it appears you're in Yuma, what about checking to have it done across the border?
