I just bought a Campbell Hausfeld HL5401 8 gallon compressor, and after break in I changed the oil.
Compressor starts, runs, cuts out and restarts fine.
The problem I’m having is trying to fill my RV tires, I can’t get it to fill over 47lbs, tanks gauge shows 120lbs and I have tried the regulator from 80 to 120. I have no leaks as pressure is not lost. Any ideas, could it be the tire chuck??

It is hard to tell where the problem lies, friend.
With tank pressure being at 120 PSI, which is a typical pressure level for this type of compressor, then, with no regulator in the discharge line, your air pressure exiting the discharge coupler would have to be 120 PSI.
Yes, it could be a faulty tire chuck or tire valve, but I doubt it. After all, if the chuck opens the valve to let air flow up to 47 PSI, unless the tire valve is closing at that pressure, the tire chuck should still flow air at the pressure coming down the line.
I suspect your air regulator gauge may not be giving you the right pressure setting, or the regulator itself may be failing.
Depending on how much time and money you want to throw at diagnosing the compressor problem, you could add a Tee to the end of the tank discharge line, move the discharge coupler to the other side of the Tee, and plumb another gauge off the Tee as a check to see what pressure is getting through the regulator.
Or, if you are careful with blowing up your tire, add a Tee before the regulator allowing non-regulated air to flow out another discharge coupler, and run 120 PSI directly to the tire chuck.
Either one would soon tell you whether it was the regulator that was the problem.
What did you decide to do?
