To the OP’s point, glad he went to Henderson and got straightened out before having a real problem. I have just ordered and am waiting for delivery of the Safe T Plus steering assist, rear trac bar and a sway bar to add to our coach when we get it out in about 5-6 weeks. We have a used 2013 Tiffin Allegro Open Road and it does ok but has quite a bit of the “dog wag” and I wanted the steering assist for help with a blowout. With that I am hoping my better half will be more comfortable driving. Hard to believe they could do such a bad job of installation. Glad you are fixed up and safe. Looking forward to finding out first hand how all this helps. Hoping I don’t feel the need for the Koni’s Upgrade.
The date code is on the tire, it will have the week and year of build, mine are 0413 meaning 4th week of 2013. Here is a flyer from Michelin, scroll down to see the code. https://www.michelinb2b.com/wps/b2bcontent/PDF/3_TB_Service_Life_RV_Motorhome.pdf Good luck in your effort to register.
