Air fill on tires

[phranc]

Crossfire pressure equalization..These work pretty slick .. Of course you buy the crossfire for your particular pressure ..
Cats Eye makes a similar system..

IMHO there is no adequate substitute for individual wheel weighing. That said, look at RV WEIGH - Mobile Weigh Station. www.rvweigh.com They are in the Las Vegas area all of March and April. That is an opportunity to get weighing done right for your coach. I had mine weighed by RV Safety Foundation, Walter Cannon, in an abandoned shopping center parking lot so facilities are not the issue. Good luck to you.

I ended up modifying one of my Milton #506 inflator gauges to do the job.

I took the foot and 6" brass pipe off the hose. I replaced the pipe with a piece of 5/16" brake tube, and got a couple adaptors to convert the straight threads on the tube to match the original 1/8" pipe threads on the foot and hose connection.

I put a slight S bend in the tube at the foot end so it could snake through the outer aluminum wheel and fit properly on the stem of the inner wheel.

On our particular setup I needed the short foot on the #506 inflator gauge. I also have a couple #516 gauges, but the longer straight foot couldn't clear the outer wheel and get the proper angle for contact on the valve stem.

Here's a link to the #516 inflator gauge so you can compare the foot to the #506

The whole process of fabricating a new tube and attaching the original foot took about 1/2 an hour. It was somewhat trial and error to get the proper bends in the proper positions. This is now a dedicated inflator/gauge that stays with the motorhome.

Have to wonder... If you had difficulty what did the dealer use when he did final vehicle prep before delivery? It would be interesting to see how they would respond if you were to stop off and ask them to show you how to measure and add air to your duals.

All the tire pressures were set at the recommended 85 psi when we got it so someone along the line had inflated them to the proper pressure.

The first few times I checked the tire pressure I did it by crawling under the coach and accessing the valve stems by reaching through the inner dual from the inside. I used either the Milton S 506 inflator or the Milton S 976 gauge. It worked but way to much of a hassle.

The modified inflator/gauge works on all the tires. It only takes a couple minutes to check all of them as opposed to 20 minutes to check just the inside duals.

Good point!
