WesternHorizon,
Thanks much for the excellent info in your post above!
I'll look into a larger diameter axle tube for the top of my 12 ton dual lift hydraulic jack.
We have a Wilson cellular antenna bolted to the top of the roof ladder feeding a 12 volt Wilson cellular amplifier inside the coach. This setup can often bring in calls and get us out on calls when our standard cell phones show NO BARS ... amazing as it seems.
Would you please supply a link as to where I can order those larger 4X4 flat-repair-in-a-can sealant kits?
The only 12 volt air compressors I would trust for reliable enough and powerful enough use on motorhome tires would be one of these 100% duty cycle VIAIR models:

The one thing I lose sleep over is -> an inner dual tire failure out in the middle of nowhere (we're rockhounds). I sure wish I could get road service for these kind of situations! I don't think that our Premium Coach-Net ERS would help us much then - even it we could get to them from our cell phones. Since our small Class C weighs only 11,800 lbs. and I keep our rear Load Range E tires at 80 lbs. of pressure, we can go a "little ways" on only one tire of a rear dual set in an emergency ... but not very fast, for very long, or on a very rough road surface.
