We just bought an 08 30 SK, really liked the floor plan and the holding tank arrangement. It's also one of the lightest units for all of the space and great basement storage. We traveled 2k miles from CO to NJ to pick it up and had no issues on the way back. Since it has the stock tires ST225-75R-15 8 ply we kept it under 65 MPH these tires are only rated for 62 MPH. They show no adverse wear in the 2k miles we traveled back to our home. We spent 3 weeks on the way back as well seeing some eastern US American history. So far we love the new to us 5er. Our last trailer was a 2000 Cedar Creek 30 ft tongue pull. Really like the 5th wheel control while towing but it did take a bit of getting used to the turning differences. I bumped a couple curbs with it but I'm getting better.
