Just went through this myself. I think I even mentioned it in another of your posts as well. As you know, went 19.5's. Nothing else gave me the capacity and piece of mind. Would I have liked to avoid the 19.5's?Before I owned them...yes. After running them for the last few months....I LOVE THEM. Maybe it is the tall sidewalls that helps or the fact I can run them at 85psi which gives a decent ride as well as carries the weight without having a little 225 at 110 psi...I might hate them then.
I won't go back...and yes, my next truck will be a dually and most likely a 5500 series truck as I will only carry more weight and larger campers in the future.
That is my opinion..
