My experience over the years is that the F53 chassis RVs drive much better if the toe-in is set at the maximum positive value in the manual. Affected much less by wind/passing trucks. Much less steering corrections needed. The downside is I have always experienced outer edge tire wear when I have the shop make sure that is what the setting is. Have had a couple RVs in the past that when I got them required a lot of correction going down the road. When checked, one had zero toe-in, the other had been slightly negative. When the tech set them to the high end of the manual value, they drove far better. We always get around 50-55K miles out of rear tires, the fronts I'll change out at 40K due to outer edge wear. I'll swap some tire wear for more relaxed driving any day. I'm guessing your RV tracks like a railroad locomotive going down the road. This is, of course, assuming that the front end is tight and you keep everything properly greased. I'm a firm believer in chassis lubricating at every oil change. I don't think you could possibly wear out the front end on an F53 if you do that. The coach body would turn to dust first.
Thank you to all who commented and I especially appreciate the info re toe on F53 RVs - that kind of info is only available from experienced RVers.
The actual stock weight on the front tires of this 30' RV is less than the any value on the weight/tire pressure chart for these 19.5 tires. I think the chart was wrong because the tread wear indicates wear would have been more even if the pressure was always 100 psi or more,
