jatrax....I would let atleast 5-8 lbs out of your tires, having the tires a max really makes the coach pound and unless you are really loaded very heavy you are well within limits running a little less pressure.
Thanks, I planned on getting weighed and setting the air pressure accordingly. But so far I've not been able to. As usual nothing I plan goes right. The tire pressure gauge I brought with me will not work on the new style valve stems being used by Phoenix. After checking at three different gas stops I finally found one that would. Now I can check the tire pressure. Tires are all about 5# low so at the next stop I pull over to get air but the machine is broken. The next day when I stop for gas I pull up to their machine it has only a tiny air chuck on it suitable for car tires, will not work on any of mine through the wheel covers.
Anyway, if 5# light sounds good, that's where I am at now.
Found some smooth road today and things drove much better. Still some vibration above 70mph but no control problems.
