Every truck with dual rear wheels has the valve stems facing this way, unless someone has replaced them with special stems to make air service easier at the expense of wheel interchangibility. It is not "poor design" rather it is a long standing wheel and tire industry standard. Anyone who claims to service trucks (including dually pickups and vans) should have the truck tire gauge and air chuck to do the job.

Someone who says one can't check air on a dually without pulling the wheels is trying to avoid the little bit of extra work involved. If you have wheel covers (or "simulators") those may have to be removed. That's been the case on cars, too, for a long time.

Special "dually" valve stems do make the job a whole lot easier. But the job is not impossible, without them.

After you checked the pressure, then try to add air! I have spent over an hour trying to add a few pounds to the outside dual. So I bought the 6 wheel kit, of solid valve stems, from "Tireman". It took me all day to install them but now checking and adding air pressure is a 3 minute job on all six wheels.

I don't know what to say except that maybe Ford uses several suppliers for their rubber valve stems and some are stiffer than others. The ones that came on our BT Cruiser were nearly impossible to work with even with the right chucks and a firm understanding of what to do. You just could not put enough pressure on the stems to seat the chuck properly without them bending out of the way. The short metal stems on our new Chevy based Freelander work very well. The rubber stems on the Ford were not strictly speaking impossible to work with but so close as to make little difference.

If you are having a lot of trouble with rubber stems a simple switch to the same length metal stems is something that any truck tire dealer can do for you at modest cost. It will make a tremendous difference. The TireMan or Borg stems are just heavenly but now that I have short metal stems that work well I am not terribly tempted to spring for the longer ones.

Where did you take it that they couldn't check the pressure? It sounds like they didn't want to help you. You don't have to take off a tire to check the pressure. It's not that hard and a duelly pressure gauge is available at any auto parts store. Filling the tires is another thing but every tire shop should have the right tool. I see the right ones even on the air compressors at the cheap gas stations.
Make it easy for yourself and get extenders. The valves will be bolted onto the hub where they are really easy to reach and fill.
And don't go back to that place with the bad service.

I had valve extenders and it was still a hassle. Now I have Crossfires and love them. Check them out at their website. I paid 175 installed.

On a trip I check tire pressure every morning, Borg replacement stems was the best way for me, saves time and aggrevation.

Steel valve stems are alot easier to check and add pressure to than rubber ones, as Klhutch stated. The rubber ones just wiggle around too much and can never get a seal on them. End up removing alot of air from the tires and accomplishing nothing.

You can call truck tire shops and tell them you want a set of long solid metal custom bent valve stems for your Ford motorhome with dual rear tires. Get estimates. I paid $180 for all six tires including fronts so I can check pressure and add air easily with beauty discs in place. Another problem, many gas stations have air pumps set for only 35lbs. I bought a 2 gallon tank Campbell Hausefeld 110volt AC compressor and air chuck with guage to conveniently maintain RV, car, an motorcycle tire pressure. Don't buy a cheap inflator intended for low pressure car tires. I know, this is ridiculous but a problem with all Class C's. BTW, you can take compressor aboard RV for long trips and run using the generator.

I think the upshot of all this is that when I replace the tires in 2 years I will get the Borg extenders. Until then I will live with the situation and cross my fingers that I don't have any problems. Still working, so MH sits in the driveway most of the summer.

Best wishes from Minnesota.
