I was wondering if I can use the onboard compressor and tanks to use an impact wrench?
I have a Porter Cable compressor ( CMB15) capable of 150 psi but it only has a 1.5 gallon tank. I'd never fit a 5 or 10 gallon tank to carry around with me.
If I can't, is there a work around.
Thanks

It won't recover fast enough to run an impact.You can use a torque multiplier. or a cordless impact. Milwaukee makes a good one.
you can but it wouldn't be very good as the Rv compressor doesn't put out enough volume so you would have to wait a lot for the air to build up
I think you could if you had an additional storage tank but you already answered that a tank is out of the question. I just bought the Milwaukee big 1/2" inpact that delivers up to 750 ft.-lbs. of maximum fastening torque, up to 1200 ft.-lbs. to remove. I have only used on a trailer tire so far and after only 1 impact it had the nuts loose. Compared to my air one it takes a few more impacts to break nut loose but after that it runs faster then the cordless one.
If you can build the pressure with the engine compressor it will keep up with an air gun. As long as the repair isn't on the engine that you need the gun for.
Your CMB15 is 2.0 CFM at 90psi and the Cummins Holset is 13.2 Or 15 CFM and you have a 5 gallon wet tank I think. I upgraded my line and hose to 1/2" for more volume. Air gun works great.

Yes the bigger issue isn't so much the compressor output but the air to the gun. Half inch hose will work better for breaking the nuts free but only if it isn't going through a quarter inch fitting between it and the tank.
I knew my compressor wasn't up to the task at 2.0 CFM. I learned that while researching impact wrenches. That's good news if the Cummins puts out 13 to 15 CFM. The impact wrenches I looked at require around 7 or 8 CFM. Looks like we have a winner here.
Thanks All
I'm a BIG fan of using whom ever's road service for tire issues.
All my years of trucking, I never (ever) considered changing tires under any condition.
Too many things that can and do go South with 100 plus lbs. of tire /wheel combo.
A decent pressure gauge is worth its weight in GOLD
and if you don't have a thumper, you need to get one. pc
+1....When we bought our first coach, it came with a monster hydraulic jack and breaker bar. The salesman was showing me the compartments and said, "here's the jack, you NEVER want to use it." ^.^d
I guess the old adage different strokes for different folks applies here.
As an owner operator I have always repaired my own flats an installed my own new tires. Just put new rubber on the crane last week
The way I see it I am saving the money to have the flats fixed and the tires mounted and the money I would spend at the gym to get the same amount of exercise. I will have to have the Foretravel tires balanced as I don't have the equipment for that. The tools in the pic are the same tools you would see when you buy tires and have them mounted.
Is it necessary to remove all the lug nuts on a Budd rear wheel to take off the hub cap?
Usually only a few of the nuts hold on the cap. Look at the nuts and see if any of the holes in the hub cap are larger than the nuts, if so those stay on. In California on the commercial trucks you just use a cap over the axle.
