I keep procrastinating doing that. Each year we head out, I promise myself to get the rig weighed, but it unravels quickly.
I recall the door sticker on our 2007 2350 (no slide out) states 60 rear, 65 front. But I add 5spi more all around to be extra careful because the tires still look like they could use some more air.....even more than 5 psi.
