Most will use them simultaneously..yours truly included...

Well, that's what I thought...so what's the deal with the posts indicating that "there might not be enough air to operate both at the same time"?

Or am I getting that all wrong?

I didn't want to get into to this, but all semi trucks use a two air supply systems. And you can drain one below 60 and not set the parking brakes on the truck. The brakes on most trucks will set right below 60 psi if both systems are depleted to this level. The air gauge has two needles. Are some trucks will have two air gauges. When I blow the air horn I never one needle go below 80 psi. The other needle never moves and stays around the 120 psi level, and keeps the parking brake released, and keeps air for the service brakes. This is all designed so if you blow a airline out you only lose air on one circuit and have control of the parking (spring brakes) and the service brakes at all times. So blowing a air horn will not set your parking brakes are deplete all your service brakes air supply, only half of it so to. Speak. The other half will retain full pressure.

Redundancy systems!

That sounds real sensible...do motorhomes with air brakes typically have that kind of backup?

Thanks!

Valid question, my comment was based on our coach being a gas powered, no air brakes, so no air supply problem.

DP coach owners would need to address the issue you question...

I do have two air tanks, gauges etc. Now, I'm no expert on how that works, but one post mentioned a 5 second blast depleting an air tank. I can't imaging laying down on these for 5 seconds, but since I already have air horns I don't anticipate these using double the air. I've never seen my air gauges drop when I laid on the existing air horn.

And BTW, they ARE going on the roof

My 2005 HR DP has two tanks and two systems as described. Like others have said, I have never seen my needle move even on the longest horn blow (before the DW yelled enough to move my hand)!!!!

Anybody up for 'speriment time?

Who's willing to go outside right now and lay on the air horn for 15 seconds while watching the air tank guages?

Advisory Side Note:

Be sure to keep this page open on the 'puter so when the neighbors/cops show up you can prove that you're really conducting Scientific Research...

Francesca is vying very hard for the 2012 SDOTY award.
It is not often that a woman even comes close to qualifying.
Way to go girl!

Just a thought.

Probably both being as I won it four or so decades running. Hint time, the last four letters represent "disturber of the year" you supply yer version for the first. I think it's just about RD&H time.

One of the truck drivers that delivered to the warehouse where I worked had locomotive horns mounted near the passenger door. Thought it was a weird place so I asked him why? He said that with his long rig he needed to make wide right turns. And a lot of times drivers would drive up on his side when he was making a turn. He used his to "remind" them that they should not be there!

Yep Roof mounted and let them rip at some of the not so smart drivers of 4 wheel vehicles!!!!
