Thanks Eric,
And thanks for your insights!  Took it out this weekend and brakes worked as usual which is not great but it is not a car.  Use the exhaust brake and time things and braking is a piece of cake.  I did let the air pressure get to low, which is now lesson learned!  Today when I came home I took the time to verify the air pressure was above 90 psi. No problems and easiest leveling I have ever had at my house.
