Well the answer is in on the tire wear problem. I took it to a Goodyear truck tire shop in Springdale, AR. The manager Dan looked at the tires in front and pronounced both are just starting to show normal wear considering they are four years old. He said no alignment is needed but did suggest I up the pressure to 105 (110 is max on the sidewall). I had him do that. He said I could lower back to 90 if it was too harsh riding but he expected we would find little difference
He also said it would stop or slow down the edge wear which makes sense. He also felt the higher pressure would make it more stable on the road because of less sidewall flex. That also made sense to me.
Having driven it several hundred miles now, I have mixed feelings about the higher pressure. Ride quality seems the same. Steering response is quicker, which is to be expected. Passing trucks and side winds seem to affect the coach more than before however. Both DW and myself felt the difference. Probably because of smaller tire contact patch and less sidewall flex to absorb sideways force. For now, I will leave it alone, but may drop the pressure back a bit. We will see.
In summary, I highly recommend the Goodyear truck tire shop in Springdale, AR, just off I-49 exit 73. I went there expecting an alignment or maybe mechanical work and told Dan so. He could have easily sold me such but did not. Because on his honesty I had him do an oil change and straighten the steering wheel which as many here know is a problem on Ford 53 chassis. The price he charged for the work was very fair.8
