Valve Extensions for Challenger Inner Duals?

It is almost impossible to check or add air to the inner dual tires on my Challenger 37KT. The valve stem comes out of the tire at an angle (does not "point" straight out) and it is 5 inches from the tip of the valve stem cap to the hole in the wheel. I would like to know what others have done as far as valve stem extenders or hose kits. Also getting ready to order EEZTire TPMS system and don't know if can use a valve extender or hose with that system. Any help appreciated. Thanks.

I had the dealer add stainless steel braided valve stem extensions and vent covers for the living area and bathroom as a condition of sale.

Here is a picture of the extension coming off one of the inner wheels.

The kit they installed retails for between 75.00 and 90.00. The cost in the dealers parts store is 82.00.

I have the same as Dave. Compatible with the TireMinder TPMS sensors.
The weight of the sensor can be an issue for some extensions - they typically recommended solid extensions. The extensions Dave and I have (in his picture) are flexible braised steel - but they are also supported near the end by metal bracket.

Great minds think alike!

I insisted on three vent covers being that I have a bath and a half and a vent over the galley. At delivery, they had not installed anything yet. My dealer, (CW), was going to install the cheapest covers they had, white opaque with the Camping World logo on them.

Before I would sign anything they replaced the intended cheap covers with Fantastic Fan Vent covers, (two smoke covers for the restrooms and one black over the galley), to match my coach, the black A/C shrouds, and the OEM galley Fantastic Fan.

The factory installed valve extenders work fine to fill my inners, so I didn't need any modification there.

I used Crossfire Crossfire - Dual Dynamics Took care of inner dual, equalizes pressure in both tires, eleminates one TPMS sensor and allows filling/adjusting both tires at the same time. Win win win.

Thanks. I had Crossfires on my last coach. Good idea.
