Driving Class C on the Beach

Alright...one more question, please? I cannot get to my inside rears to even check the air, never mind air down/up. I have tried so many different extensions and they all seem to fail in short order, leaving me with a flat. What extensions do you use? I know there is a guy in Ca., that makes them to order but he doesn't ship to Canada, so I am searching.

Gary,

Do you mean these kind of valves to make airing down/up your tires trivial ... I wonder if this outfit would ship to Canada:

Probably as you know, a compressor that you can carry with you to air up your tires is not an easy choice. It takes an expensive 12 volt DC one (like the off-roaders use) or a less expensive 120 volt AC one powered from your built-in generator blow up your RV's tires, time after time, reliably. Many of the less expensive portable compressors are for intermittent use only, so they must be allowed to rest for a length of time after so many minutes of continuous use. "Intermittent use only" is unacceptable in a tire inflation portable compressor, IMHO. I carry a 120 volt AC one that can do the job anywhere (assuming the Onan will start!) with no rest periods.

By the way, considering all of the weight on a Class C's tires, I wonder what kind of abuse (mostly in their sidewalls) they are suffering when still carrying this weight while aired down? I would be afraid of rolling aired down RV tires right off their rims. Obviously, I guess one should only travel very short distances - and not on any side slopes ... level surfaces only - with their Class C tires less than fully inflated so that the tires keep their shape enough to stay on the rims.
