Class A air compressor?

On a Diplomat there is an valve outlet for air in compartment under driver. Went to hardware store got some fitting and 50' of air hose (plus a HomeDepot hose reel) and have a way to air up tires 95# in front and 90# in back for when tires heat up they are running very close to 110#. Was such a hassle driving into a station and air hoses be broken. Motorhome with air brakes has an air compressor already.

Go to Sears, Home Depot or Lowes and get a 120v AC pancake compressor that will go to 140-150 psi. If you depend on your engine compressor you will be a long time filling tires, unless you have unlimited patience. I run 120 in the front and 105 in the rear. The engine compressor cuts in at 90 and out at 120. If you are near or below your desired psi you aren't going to get air in the tires or you will have to bleed air to get the engine compressor working to get the pressure up where it will push air into the tires. Cost for the store compressors should be in the $100-$200 range depending on sales.
Good luck and safe travels!

Exactly
I use a Porter Cable 150psi compressor, stored at the back of a storage bay pull out tray. I can run it off the inverter or the generator.
Buy a 50 foot Flex Ell hose ( no kinks and takes up little room) and a truck model double headed air chuck ( they slip onto the valve stem and lock onto the threads).

Also alkillion Welcome to the forum.

There is much information available here. Keep asking questions, soon you will be helping others

Thanks folks. I've got a lot to learn about a diesel rig.

The Winnabago website shows your MH would have a Cummins ISB for power not a CAT.

With a Freightliner XCS chassis, Check in the front driver side basement cabinet for an air compressor connection.

Why carry something you'll never use..:h....use the engine for air.

Since the coach is new, you need to weigh it first. Then using those figures, check the weight tables for the correct air pressure. Make sure your coach is reasonably full on stuff you'd normally take with you on a trip when you get on the scales. For now, 110 will be fine until you have actual weights, then I think you'll find 110 is way too high. I run 110 on my steer axle, 315/22.5 100 on the drive axle, 295/22.5 and 95 on the tag. These pressures are 5PSI above the recommended PSI based on my weights. The 5PSI if for my personal comfort zone....Dennis

Note: The IDEAL method of weighing is to have each corner weighed but that's expensive and not too easy to find someone who can do it. You can axle weigh your coach at any CAT scale usually found at Flying J or a truck stop. Moving companies, grain elevators etc have them as well...D

Check and see if your new rig does not have and auxiliary air chuck already. If not ad one or have a diesel shop do it for you.
That thing will put out more are than you will ever need.

Your profile doesn't list what year or model your Forza is, but looking at the specs on the newer ones, they have air brakes. So all you should have to do is get an air hose and chuck if yours has them also. Much cheaper.
