Glad you got it fixed safely. I don't know what your individual corner weights are, but that doesn't sound like enough air pressure.
I always inflate {and adjust} for the load I will be running as it can vary by almost a thousand pounds depending on whether or not {and what} we are towing/loading. We often run at or very near our max GVWR of 11,500# {I have a 2011 E-350 chassis - the coach is a 2012}. I have 3,800# on the front axle and 7,700# on the rear. Per the Michelin load/psi tables I run at 65 psi front and 75 rear adding in a 10 percent fudge/safety factor. The ride and handling are awesome. I am running HD Bilsteins and tow with my air bags at 50 psi with excellent results.
Running the fronts on most 25' or less Class C's at 80 psi per the door stickers {which are a bad joke}, will reduce the contact patch to the point that it will handle like a pig on skates and be blown all over the road by passing trucks and/or cross winds. Putting 80 in the rears would be serious overkill las at 80 they are rated for 2,640# of load X 4 = 10,560# to carry a 7,700# load. This also creates a very stiff ride that will beat you to death and shorten tire life.
