You are spot on in your comment about being sure to weigh your coach before adding more tile.  My coach is a 2007 with 365s on the front and when I have full fresh water and fuel I am within about 175 pounds of being at my max weight on my front driver side tire.  I had the chance of having tile installed throughout but had to just have the carpet replaced for I would have gone over my max tire capacity, even with 365s.  I met a few people at Newell having tile installed throughout their coach and the first thing I asked them was if they had weighed their coach before adding the tile.  I got the "Deer in the Headlights" look.  Then they replied that Newell was installing it so it must be OK.  I know my coach when it was originally built only had 315s on the front and there was no way it could have been meeting its tire capacities - unless of course you were traveling VERY light.  I am the 2nd owner and Newell installed the 365s before I bought it from them.
