Everything is still original on ours, although I want to do some upgrades. I've heard a lot of good things about Bilsteins, and that's where I intend to start ... when I get to that.
As far as getting down the road, though, it's not terrible. Of course, it's never going to be a cornering machine, but on an interstate, it does great.
My biggest concern after this weekend is getting something installed to stabilize it while we're set up and living in it. My oldest daughter flops around a lot when she sleeps, and EVERYONE felt it this time. So that's my #1 priority before our next trip ... which is in 2 weeks. Not much time to investigate my options, but I'm sure I'll think of something.
Aside from that, though, I still love it.
