Internal air for tires? Holiday Rambler

[grthigpen]

Does anyone use the internal air system to air up their tires? Mine has the air fitting in the front compartment next to the Gen... thx

I have a set up for using my coach air to fill the tires. It works but has some drawbacks. First is you need to have the pressure near max to fill tires so you have to bleed the air once it is below the target pressure to activate the compressor to get it back up to a high enough pressure to fill the tires. This is especially hard on the steer tires as they have a higher pressure. Secondly you need to carry a long hose as well has the gauge and chuck so there is still somewhat of a storage issue. On the other hand the other option of a stand alone compressors takes up even more valuable storage space.

A long air hose was one of the first accessories I bought for my coach. If I need air on a regular basis, I'll buy a compressor. That hasn't happened yet.

Some people will tell you how easy it is to air off coach system. Others like myself will tell you it might make your brain vapor lock. Get a Craftsman 150 lb compressor and it will be much easier. Doesn't take up much room.

The on-board compressor outlet on my coach is in the compartment under the driver where the propane tank is! I've seen where some folks say the one by the generator is for towing companies to connect to for towing the MH!

Check that front fitting beside the generator to see if you can actually get air there. On my coach, that fitting is to put air into the coach, primarily for a tow truck to be able to put air into the coach system to tow it.

On my coach, there's another fitting at the back of the coach in the engine compartment to get air. Others have it in the propane bay.

mine is like Joe's

Mine is next to the propane tank, too. I don't think the one in the gen compartment can be used to air tires.
One note: I left the air hose connected and the sharp bend caused an air leak at the chuck that drove me nuts before I happened to jostle it and heard it hiss. I now disconnect it after each use.

Cheers,

That depends on your coach. It's been said on this board many times ... 'These rigs are like snowflakes'!
I have 4 air connectors on a single manifold in my generator compartment. Top one is the air coupler you can plug into to air tires etc. 2nd is for external air supply (tow truck), and doubles as the wet tank drain. Bottom two valves are stricktly drains, (front and rear dry tank).

Carried compressor for first two RV's. Present one has outlet for being towed and one for adding an air hose to. I have mounted a reel w/75' (to reach a toad) of air hose by the generator. When (on steering wheel) I press the cruise button and the set button, the rpm's stay at 1500, and pressure stays at 115/125. This will continue to give enough pressure to reach 90 lb./100 lb. which is what I use on my tires. This is not for filling all tires, and only used once. Use truck stops when I have to add air to a bunch of tires. So far this works well.

The compress or air brakes on a diesel pusher is a very expensive tire inflater. Typical replacement is about $800 plus labor.

The compressor is not designed for the the volume and pressure that tires require. The effective pressure for the air brake system is 100-120 psi, the switch-on switch-off points. Not really enough pressure to top off a 115 psi tire.

You can crank up the compressor cut-off to 130 psi and be going to the parts store sooner for a new compressor.

Any electrical compressor or a CO2 system is lower in cost and better than using your engine compressor.

With an "on board" air compressor, (and with most "stand alone" air compressors), you have to do that if/when you need to add more than a few PSI to a tire.
Only the large compressors, (at tire shops, truck stops and the like), have the capacity to air up MH tires without that PITA procedure.

My Power Tank CO2 system is set for 170 psi, more than enough for any 22.5 tire. I can go higher but no need. And it is silent.

X2 just don't ask me how I learned this Fact. A 40 footer on a lowboy isn't pretty.
