I in the market for another motorhome. I had the F53 and could never got it to track straight. Yes, I did a bunch of upgrades and changes and it got better but was never right. I’m considering going...
I have had 2 P 30 type chassis and have never had the bad driving problems people complain about. If they are properly aligned and in good condition I think they drive fine. My biggest complaint about them was the air bags inside of the front springs. On the one I have now they blew out on a trip and when I got home I put the super springs in it, had it aligned, and that made it sit leveler than before and drive great.
