Looks great! Is this your first motorhome? Do you plan to use it just for camping or are you going to pull a trailer to a race track or horse event? Cycles or a smart car in the garage?
My tanks are close. 200 fresh, 75 gray, 25 black. Those black/gray ratios work pretty well for us. Usually the black will beat the gray to full. Once I filled the gray before the black got full.
I use a Pressure Pro tire pressure monitor system and really like it. Might want to think about one of those. I most often pull a enclosed car trailer and it works good to monitor the tires on the trailer too since I probably wouldn't be able to feel a tire blow on that.
My truck had a very rough ride up front when I got it. I just assumed that's the way it was supposed to ride. When I replaced my steer tires we found nothing inside them to balance them. I put the Dyna Beads in the new steers. Wow, what a difference. If you think yours is rough maybe check that.
